  • Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board
    Precio:  $2,089.00

    Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board

    -Titulo Original : Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board-Fabricante : ADAFRUIT-Descripcion Original: TB6612 motor driver // 1.2A per channel // Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V // Dimensions: 27mm x 19mm x 3mm / 1.1" x 0.7" x 0.1" // Weight: 1.8g // Spin two DC motors, step one bi-polar or uni-polar stepper, or fire off two solenoids with 1.2A per channel using the TB6612. These are perhaps better known as the drivers in our assembled Adafruit Motorshield or Motor HAT. We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto. We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the standby enable pin. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive 2-4 solenoids (only two can be active at a time, on opposite bridges), two DC motors bi-directionally, or one stepper motor. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 3A but that's just for a short amount of time, like 20 milliseconds. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver! There's two digital inputs per H-bridge (one for each half of the bridge) as well as a PWM input per driver so you can control motor speed. Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V! This wont work well for 3V motors. Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included. Check out our handy tutorial on assembly and wiring...

With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. If you need a 1A battery charger, smart load-sharing, and 1A iOS resistors, check out the Powerboost 1000C Like our popular 5V 1A USB wall adapter , we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' for long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. The PowerBoost 500C has at the heart a TPS61090 boost converter from TI . This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs!Synchronous operation means you can disconnect the output completely by connecting the able pin to ground. This will completely turn off the output2A internal switch (~2.5A peak limiting) means you can get from a 3.7V LiPoly/LiIon battery. , just make sure your battery can handle it!Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo/LiIon battery usageOnboard 500mA charge-rate 'iOS' data resistors.

    -Titulo Original : Adafruit IC Socket - for 16-pin 0.3 Chips - Pack of 3 [ADA2203]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2203 // Stock Type: Components & Parts >> Sockets/Connectors // In Stock & Ready to Ship // An IC (Integrated Circuit) socket allows you to insert and remove chips easily from an assembled kit or project This item contains 3 of the 16 pin 0.3 wide version. Best used with chips that have 16 pins (2x8) and have 0.3 pin spacing. These are often used for soldering into a Perma Proto or PCB so that you can replace and swap chips easily. What's nice about IC sockets is that they are the same pin spacing and size so you don't have to redesign the board! For our example photo, we put the socket into an  Adafruit Perma-Proto Breadboard but any solderable PCB or protoboard will work great. Not recommended for solderless breadboards, the pins are not long enough...
  • Adafruit Silicone Elastomer 4x4 Button Keypad - for 3mm LEDs

    Adafruit Silicone Elastomer 4x4 Button Keypad - for 3mm LEDs

    -Titulo Original : Adafruit Silicone Elastomer 4x4 Button Keypad - for 3mm LEDs [ADA1611]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1611 // Stock Type: Components & Parts >> Switches // In Stock & Ready to Ship // So squishy! These silicone elastomer keypads are just waiting for your fingers to press them. Go ahead, squish all you like! (They're durable and easy to clean, just wipe with mild soap and water) These are just like the light up rubber buttons you find on stuff like appliances and tools, but these are open source and easy to integrate into your next project. Each button is 10mm x 10mm square and 10mm tall. There is 5mm of grid spacing between the buttons. You can 'tile' the button pads edge-to-edge and they'll grid up correctly. You can also cut the pads down if you like, the silicone is very soft. The way they're molded, they give about 3mm of travel when pressed for a very satisfying feel. They are completely quiet, however. On the bottom of each button is a conductive pad ring which can close a properly design contact underneath. We have an EagleCad library which has objects for the buttons and optional LEDs so you can use them in your next PCB design. Each button is 10mm tall and can fit a 3mm LED inside quite easily. 5mm LEDs are too big, so stick with 3mm here. The LED is optional, having it or not does not affect the 'action'. but it's nice to backlight buttons. Diffused LEDs are best, so check out our offerings: the blue, white and red look best, if you're sourcing your own LEDs go for something with 300mcd or greater brightness. Diffused looks better than not. Chances are you don't want to make your own PCB, so pick up an Adafruit Trellis, our tile-able driver which can control 16 LEDs + these 16 buttons over I2C Check out our github repository for 3D CAD files and an Eagle library with ready-to-go object...

  • Adafruit AC, DC & Servo Motors Sub-Micro Servo SG51R (1 piec
    Precio:  $2,209.00

    Adafruit AC, DC & Servo Motors Sub-Micro Servo SG51R (1 piec

    -Titulo Original : AC, DC & Servo Motors Sub-Micro Servo SG51R (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2201 // Stock Type: Robotics & CNC >> Robotics // In Stock & Ready to Ship // This is just about the cutest, tiniest little micro servo we could find, even smaller than the 9 gram micro servos we love so much.  It can rotate approximately 180 degrees (90 in each direction) and works just like the standard kind you're used to but  much smaller .   You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. Of course, its not nearly as strong as a standard servo. Works great with the Motor Shield for Arduino or by just wiring up with the Servo library. Comes with a few horns and hardware. To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the  Servo library  included with the Arduino IDE ( see here for an example sketch ). Position 0 (1.5ms pulse) is middle, 90 (~2ms pulse) is all the way to the right, -90 (~1ms pulse) is all the way to the left...
  • Adafruit i2c / SPI Character LCD Backpack [ADA292]
    Precio:  $2,729.00

    Adafruit i2c / SPI Character LCD Backpack [ADA292]

    -Titulo Original : Adafruit i2c / SPI Character LCD Backpack [ADA292]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 292 // Stock Type: LCDs & Displays >> Character // In Stock & Ready to Ship // LCD backpacks reduce the number of pins needed to connect to an LCD. LCDs are a fun and easy way to have your microcontroller project talk back to you. Character LCDs are common, and easy to get, available in tons of colors and sizes. We've written tutorials on using character LCDs with an Arduino (or similar microcontroller) but find that the number of pins necessary to control the LCD can be restrictive, especially with ambitious projects. We wanted to make a 'backpack' (add-on circuit) that would reduce the number of pins without a lot of expense. By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD. For Arduino users, we provide a easy-to-use library that is backwards compatible with projects using the '6 pin' wiring. The breakout comes with a 2-pin and 3-pin terminal block as shown (you can snap it together to make a 5-pin terminal and then solder it to the backpack for easy wiring) This backpack will work with any 'standard' character LCD, from 8x1 to 20x4 sizes! As long as they have a 16-pin single-line connection header at the top. We carry a few LCDs that work great . We suggest using our blue & white 20x4 or 16x2 LCDs. It does not work with the 16x2 OLED displays. You can try to connect our RGB 16x2 or 20x4 LCDs up but this backpack will not control the RGB backlight so you'll have to use the backpack only for the 14 digital IO pins (pins #1-14) and connect the backlight pins (#15-#18) directly to your microcontroller with 4 extra wires for color/PWM control as if they were just an RGB LED. For advanced users, this project can be used for general purpose I/O expansion, the MCP23008 has 8 i/o pins (7 are connected) with optional pull-ups, the SPI 74HC595 has 7 connected outputs. For a detailed tutorial on usage, including an Arduino library, wi...

    Adafruit Arcade Button - 30mm Translucent Pink [ADA472]

    -Titulo Original : Adafruit Arcade Button - 30mm Translucent Pink [ADA472]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 472 // Stock Type: Components & Parts >> Buttons // In Stock & Ready to Ship // A button is a button, and a switch is a switch, but these translucent arcade buttons are in a class of their own. They're the same size as common arcade controls (often referred to as 30mm diameter) but have some nice things going for them that justify the extra dollar. First, they look fantastic, all 6 colors have a crystal translucent glossy look. Although they do not have LEDs built in, we're confident that sticking a diffused LED into the body would make it light up very nicely. They are also shorter than cheap arcade controls, and snap into place, so you only need 1.5 of depth (1.25 if you bend the contacts over). The button action is smooth, without a strong click, yet you can definitely feel when the button is pressed. A tiny micro-switch is pre-installed, with gold plated contacts...

Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's Adafruit's lowest-cost CircuitPython programmable board! It is the same form factor as the original ATtiny85-based Trinket. The Trinket M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. It's just as small, and it's easier to use, so you can do more. The most exciting part of the Trinket M0 is that while you can use it with the Arduino IDE, it is shipped with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language.

    Adafruit Resistive Touch Screen to USB Mouse Controller - AR

    -Titulo Original : Adafruit Resistive Touch Screen to USB Mouse Controller - AR1100-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1580 // Stock Type: Breakout Boards >> Touch // In Stock & Ready to Ship // Getting touchy performance with your screen's touch screen? Resistive touch screens are incredibly popular as overlays to TFT and LCD displays. If you want to connect one to a computer you need something to handle the analog to digital conversion. Most converters we've found are not very easy to use, and are 'fixed' - making them difficult to calibrate. The AR1100 is a nice chip that solves this problem by acting as a touch->USB converter and also comes with calibration software. The calibration software is Windows only, but once you've calibrated you can use the screen on any OS. The AR1100 shows up as a regular Mouse or Digitizer HID device so no drivers are required. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're probably used to that.This breakout board features the AR1100, which has both USB and UART interfaces available. 99% of the time, you'll want to use the USB interface but there is some functionality for getting TTL UART data out (see the datasheet for details) There is also a red LED that lights up to indicate when a touch has been detected. For the screens that have 1mm pitch FPC cables, you can plug the cable right into the connector. The majority of medium/large touchscreens have that kind of connector. If you have another kind of touch screen, the four X/Y contacts are available on 0.1 pitch breakouts so you can hand-solder or wire them. We set this breakout up for 4-wire sensing only. You can pretty much just plug and play to get started, for more details including calibration software, check out the AR1100 page . Plug any 1mm-pitch 4-wire resistive touchscreen to the on-board FPC connector, when you plug into a computer's USB port you should see a new device and touching the screen will cause the mouse cursor to move around...

This adapter is backwards compatible with v2.1 and earlier, but also supports the latest v4.0/Bluetooth Low Energy. Inside lies a CSR8510 Bluetooth USB host. We've used this with great success on a Windows 7 computer, installing as a 'generic' Bluetooth device, but we expect it to work just fine with any modern computer as this chipset is very common. So far we've tested it to communicate with Bluetooth data modules only. Revision note: As of Friday, August 28th, 2015 these now have unique MAC addresses! That's great because now you don't have to worry about using two or more of them at once, handy for people turning these into beacons. Drivers for CSR Bluetooth modules are built into Windows XP/7/8/10 so you do not need to install any software or download anything: other bluetooth drivers or 'stacks' such as BlueSoleil are not as good as the Windows stack and will cause problems. Just plug it in and let windows auto-install the BT driver, it may take a few minutes! For Linux, use Bluez which works great, our Pi tutorial will be similar to your favorite distro Bluetooth 4.0 USB Module (v2.1 Back-Compatible) ( 3:32 ...

    -Titulo Original : Adafruit Electroluminescent (EL) Panel - 10cm x 10cm Blue [ADA624]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 624 // Stock Type: EL Wire/Tape/Panel >> EL Panels // In Stock & Ready to Ship // EL panel is the big sister to EL wire - it has the same glow effect but with a flat shape instead of a round shape. This is a big sheet of flexible plastic coated with EL material so its like one big glowing square. It emits an even glow over the entire shape. The glowing part of the panel is 10 cm x 10 cm (approx: 4 x 4). There's a plastic coating is about 10.4cm x 10.4cm. Its covered in what seems to be PVC, the tape is thus weather-proof - but note that the connectors are NOT waterproof, just a bit of heatshrink. This isn't something we would suggest leaving outdoors for extended periods. You can attach it by sewing through the clear plastic edging, or gluing the back to a flat surface. It is flexible but will crease and damage if folded. You can cut the panel up as long as the shape you cut out is continuous and has the JST cable attached. This panel is a blue color when lit and appears blue when off. Because EL tape has more surface area than wire, it requires a more powerful inverter. We suggest you use our 4xAAA inverter which is strong enough to power a single panel at once - plug it in and turn it on! For more permanent installations, the 12V EL inverter can also power a single panel and run off 8xAA batteries or a wall adapter....

No way dude! 7-Segments for life!A Feather board without ambition is a Feather board without FeatherWings! This is the  Adafruit 4-Digit 7-Segment LED Matrix Display FeatherWing ! This 7-segment FeatherWing backpack makes it really easy to add a 4-digit numeric display with decimal points and even 'second colon dots' for making a clock. This version does not come with an LED matrix. Its also available in combo packs of  Blue , Green ,  Red ,  White , or Yellow which we recommend since you'll know you have a working LED matrix. Not guaranteed to work with any other 7-segment modules.7-Segment Matrices like these are 'multiplexed' - so to control all the seven-segment LEDs you need 14 pins. That's a lot of pins, and there are  driver chips like the MAX7219  that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these LED Matrix FeatherWings come in!The LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (HT16K33) does the multiplexing for you. The Feather simply sends i2c commands to the chip to tell it what LEDs to light up and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since it uses only I2C for control, it works with any Feather and can share the I2C pins for other sensors or displays.The product kit comes with:A fully tested and assembled Adafruit 4-Digit 7-Segment LED Matrix Display FeatherWingTwo 16-pin headersA bit of soldering is required to attach the matrix onto the FeatherWing but its very easy to do and only takes about 5 minutes!  Note : Feather board and seven-segment display are not included, but we ...

    Adafruit SI1145 Digital UV Index/IR / Visible Light Sensor [

    -Titulo Original : Adafruit SI1145 Digital UV Index/IR / Visible Light Sensor [ADA1777]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1777 // Stock Type: Sensors >> Light/Color/Photo // In Stock & Ready to Ship // Remember when you were a kid and there was a birthday party at the pool and your parents totally embarrassed you by slathering you all over with sunscreen and you were all MOM I HAVE ENOUGH SUNSCREEN and she wouldn't listen? Well, if you had this UV Index sensor connected up to an Arduino you could have said According to this calibrated SI1145 sensor from SiLabs, the UV index right now is 4.5 which means I do not need more sunscreen and she would have been so impressed with your project that you could have spent more time splashing around. The SI1145 is a new sensor from SiLabs with a calibrated light sensing algorithm that can calculate UV Index. It doesn't contain an actual UV sensing element, instead it approximates it based on visible & IR light from the sun. We took this outside a couple days and compared the calculated UV index with the news-reported index and found it was very accurate! It's a digital sensor that works over I2C so just about any microcontroller can use it. The sensor also has individual visible and IR sensing elements so you can measure just about any kind of light - we only wrote our library to printout the 'counts' rather than the calculate the exact values of IR and Visible light so if you need precision Lux measurement check out the TSL2561. If you're feeling really advanced, you can connect up an IR LED to the LED pin and use the basic proximity sensor capability that is in the SI1145 as well. We wrapped this nice little sensor up on a PCB with level shifting and regulation circuitry so you can safely use it with 3 or 5V microcontrollers. If you are using an Arduino, we've got a lovely tutorial and library already written up with example code so you can quickly read sensor readings and the UV index in under 10 minutes. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to so...

We designed Feather to be a new standard for portable microcontroller cores. This is the Feather M0 Basic Proto, it has a bunch of prototyping space built right in. We have other boards in the Feather family, check'em out here! At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip. To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge...

    -Titulo Original : Adafruit DS2413 1-Wire Two GPIO Controller Breakout [ADA1551]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1551 // Stock Type: Breakout Boards >> Other // In Stock & Ready to Ship // You're too cool for I2C, and SPI has so many wires, 8-bit parallel... how can that be fashionable!? You are a 1-Wire kinda gal, and you want more 1-Wire breakouts in your life to complement all of your great engineering. Well rock on, because here you go, it's a 1-Wire controller with two open-drain GPIO. You can put as many of the DS2413's as you want on a single I/O line, each one is uniquely addressable and shares the single I/O pin happily. The two controllable I/O lines (PIOA and PIOB) can be used as inputs or outputs. They are open-drain, so if you want to power an LED or something, you'll need a remote power supply (see Maxim's product page for more details ) We have a basic Arduino sketch that uses the OneWire library to communicate with this chip. Don't forget to add the 4.7Kohm resistor from I/O to your 1-Wire controller power supply (3.3V - 5V) on the Arduino side of the wires. DS2413 1-Wire Two GPIO Controller Breakout ( 4:45 ...

    Adafruit Small Reduction Stepper Motor - 5VDC 32-Step 1/16 G

    -Titulo Original : Adafruit Small Reduction Stepper Motor - 5VDC 32-Step 1/16 Gearing [ADA858]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 858 // Stock Type: Robotics & CNC >> Robotics // In Stock & Ready to Ship // This is a great first stepper motor, good for small projects and experimenting with steppers. This uni-polar motor has a built in mounting plate with two mounting holes. There are only 32 step (11.25 degree) per revolution, and inside is a 1/16 reduction gear set. (Actually its 1/16.032 but for most purposes 1/16 is a good enough approximation) What this means is that there are really 32*16.032 steps per revolution = 513 steps! The shaft is flattened so its easy to attach stuff to it with a set-screw. A perfect first stepper motor and works well with the Motor Shield for Arduino. The gearing has a few side effects which are important to note. First, . It also means you shouldn't use interleaved or micro-stepping to control or it will take forever to turn. Instead use single or double stepping. The torque is fairly high but its slower than un-geared steppers - we maxed out at about 50 RPM by over-driving it a bit with 9VDC. At 5V try to stick to under 25 RPM To use with the Adafruit Motor Shield, connect red to ground (middle), orange and pink to one motor port (say M1) and blue and yellow to the other motor port (say M2). So in order, thats: orange - pink - red - blue - yellow. Then just use the example code that comes with the Adafruit Motor Shield library and set the constructor to and the speed at 5 RPM by calling . Otherwise, you can also wire it up with some transistors and use the Arduino Stepper librar...

    -Titulo Original : Adafruit Bluefruit LE Sniffer - Bluetooth Low Energy (BLE 4.0) - nRF51822 - v2.0 [ADA2269]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2269 // Stock Type: Wireless >> Bluetooth // In Stock & Ready to Ship // Interested in learning how Bluetooth Low Energy works down to the packet level? Debugging your own BLE hardware, and trying to spot where something is going wrong? Or maybe you're writing a custom application for your phone or tablet that needs to talk to existing BLE hardware, but you don't know how it works beneath the surface? We have the perfect tool for you!This Bluefruit LE Friend is programmed with a special firmware image that turns it into an easy to use Bluetooth Low Energy sniffer. You can passively capture data exchanges between two BLE devices, pushing the data into Wireshark, the open source network analysis tool, where you can visualize things on a packet level, with useful descriptors to help you make sense of the values without having to crack open the 2000 page Bluetooth 4.0 Core Specification every time.Plug it into your development machine, fire up the special sniffer bridge SW, select the device you want to sniff, and it will fire up Wireshark for you and start pushing data in via a live stream (using Nordic's Windows software), or save to a pcap file that you can analyze with Wireshark later. Please Note :  You can only use this device to listen on Bluetooth Low Energy devices! It will not work on Bluetooth (classic) devices. The Nordic Wireshark-streaming sniffer software is currently Windows only. We have example code using the python API that will work on any OS to log the sniffed data to a pcap file for analysis so you can use this sniffer with any OS with python.The sniffer firmware cannot be used with the the Nordic DFU bootloader firmware, which means that if you want to reprogram this devices you must use a J-Link (and, likely, a SWD adapter + SWD Breakout ) You cannot over-the-air reprogram it.
