    Adafruit 74LVC245 - Breadboard Friendly 8-bit Logic Level Sh

    -Titulo Original : Adafruit 74LVC245 - Breadboard Friendly 8-bit Logic Level Shifter [ADA735]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 735 // Stock Type: Components & Parts >> IC & Transistors // In Stock & Ready to Ship // Most of our customers love using the Arduino for prototyping, design and invention but find themselves stuck when trying to connect the Arduino to the latest sensors, displays, controllers, interfaces, etc. as they are almost all 3.3V logic these days. We try to solve this problem by having all our breakout boards be 5V compatible or when that's not possible, including a level shifter chip but there are still thousands of tempting devices out there. This chip solves the problem of how to interface 3.3V logic devices to a 5.0V logic chip such as the Arduino. Most 3.3V devices do not like being run with 5V signals and can be damaged or flaky. The 74LVC245 is designed so that even when it runs at 1.8V, it still happily accepts 5V signals in one pin and converts it to a lower logic level on the opposite pin. This chip is only for digital signals, it doesn't convert analog signals (you need an op amp for that). It has 8 pipes it can convert but it won't work with bi-directional/pull-up based devices such as I2C or 1-Wire. It does work great for SPI, Serial, Parallel bus, and other logic interfaces. Using it is simple. We suggest checking out the 74LVC245 datasheet for details but essentially: connect VCC to your logic level you want to convert to (say 3.3V), Ground connects to Ground. Wire OE (output enable) to ground to enable the device and DIR (direction) to VCC. Then digital logic on the A pins up to 5V will appear on the B pins shifted down to the VCC logic...
  • Adafruit Extra-long force-sensitive resistor (FSR) - Interli

    Adafruit Extra-long force-sensitive resistor (FSR) - Interli

    -Titulo Original : Adafruit Extra-long force-sensitive resistor (FSR) - Interlink 408 [ADA1071]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1071 // Stock Type: Sensors >> Touch // In Stock & Ready to Ship // FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost. This sensor is a Interlink model 408 FSR with a massive 1/4-inch x 24-inch sensing region. You can press anywhere along the strip and the pressure will be recognized. Note that this sensor can't detect where on the strip you pressed (for that, check out our ribbon soft pots ). FSRs are basically a resistor that changes its resistive value (in ohms Ω) depending on how much its pressed. These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSRs you should only expect to get ranges of response. While FSRs can detect weight, they're a bad choice for detecting exactly how many pounds of weight are on them. FSRs are made of plastic and the connection tab is crimped on delicate material. The best way to connect to these is to simply plug them into a breadboard or use a clamp-style connector like alligator clips, female header, or a terminal block. It is possible to solder onto the tabs but you must be very fast because if your iron is not good quality or you dally even a few seconds, you will melt the plastic and ruin the FSR!

    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 Automotive Gauge Stepper Motor - x27.168 [ADA2424]

    -Titulo Original : Adafruit Automotive Gauge Stepper Motor - x27.168 [ADA2424]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2424 // Stock Type: Robotics & CNC >> Robotics // In Stock & Ready to Ship // This stepper motor is a little different than the large NEMA-17 types you may be used to. These are often used in gauges for motorcycles and cars to replace the old-style fully-analog type. They have extremely fine step precision of about 1/2 a degree per step, 600 steps for single stepping, fast response for quick movements, and a range of  ~315° degrees. Their smooth motion makes good for small projects that need a dial indicator, and more precision motion than you may get with a needle gauge.Since this is a bi-polar stepper motor you do need to have some sort of H-Bridge to drive it. A L293D or TB6612 will do the job nicely. If you have a microcontroller that can drive 200 ohm loads you might be able to use the direct pins without extra MOSFETs, just remember to include kickback/flyback protection diodes!Note that the motor is quite 'weak', not good for moving anything but a light indicator. We include a red-line dial that fits nicely on top by pushing onto the needle shaft...

    Adafruit LED Lighting Development Tools NeoPixel FeatherWing

    -Titulo Original : LED Lighting Development Tools NeoPixel FeatherWing - 4x8 RGB LED Add-on For All Feather Boards-Fabricante : ADAFRUIT-Descripcion Original: A Feather board without ambition is a Feather board without FeatherWings! This is the NeoPixel FeatherWing, a 4x8 RGB LED Add-on For All Feather Boards! Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and make your Feather board strut like a peacock at a rave. Put on your sunglasses before staring into these 32 configurable eye-blistering RGB LEDs. Arranged in a 4x8 matrix, each pixel is individually addressable. Only one pin is required to control all the LEDs. On the bottom we have jumpers for the DIN line to any of the I/O pins on a Feather. You can cut the default jumper trace and use any pin you like. To make it easy to start, the LEDs are by default powered from either the USB power line or Battery power line, whichever is higher. Two Schottky diodes are used to switch between the two. This power arrangement is able to handle 1 Amp of constant current draw and maybe 2A peak, so not a good way to make a flashlight. It's better for colorful effects. A level-up shifter converts the 3.3V logic of the Feather to the power line voltage. If, say, you need MORE blinky, you can chain these together. For the second Wing, connect the DIN connection to the first Wing's DOUT. Also connect a ground pin together and power with an independant 5V supply to keep from loading the power supply too much.

We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you'll get much truer color than most sensors, since humans don't see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass or fabric. To make sure you get consistent color, we specified a nice neutral 4150°K temperature LED with a MOSFET driver onboard to illuminate what you're trying to sense. The LED can be easily turned on during sensing and turned off afterwards to save power. Connect to a Flora via I2C and our example code will quickly get you going with 4 channel readings. A detailed tutorial is in the works, till then, check out our Arduino library and follow our tutorial to install . Sew up the sensor by connecting 3V to 3V Flora output, Ground to common ground, SCL to I2C Clock and SDA to I2C Data on your Flora. All the pins line up and you can chain another sensor such as a lux sensor or accelerometer. Restart the IDE and select the example Flora sketch and start putting all your favorite fruit next to the sensor element! Flora Color Sensor - TCS34725 ( 22:21 ...

    Adafruit Memory IC Development Tools SPI Non-Volatile FRAM B

    -Titulo Original : Memory IC Development Tools Adafruit SPI Non-Volatile FRAM Breakout - 64Kbit / 8KByte (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1897 // Stock Type: Breakout Boards >> Storage // In Stock & Ready to Ship // FRAM, or Ferroelectric Ram, is the coolest new data storage method that all the fashion magazines are talking about. Oh wait, no that's quilted handbags. But FRAM is pretty damn cool too! It's similar to Dynamic random-access memory, only with a ferroelectric layer instead of a dielectric layer. This gives it stable handling (the bytes you write are non-volatile) with dynamic responsiveness (you can write them very fast!) Now, with our SPI FRAM breakout board you can add some FRAM storage to your next DIY project. FRAM allows for a lower power usage and a faster write performance. It's excellent for low-power or inconsistent-power datalogging or data buffering where you want to stream data fast while also keeping the data when there's no power. Unlike Flash or EEPROM there's no pages to worry about. Each byte can be read/written 10,000,000,000,000 times so you don't have to worry too much about wear leveling. This particular FRAM chip has 64 Kbits (8 KBytes) of storage, interfaces using SPI, and can run at up to 20MHz SPI clock rates. Each byte can be read and written instantaneously (like SRAM) but will keep the memory for 95 years at room temperature. We picked up the largest chip that has SPI and is also 5V compliant. You can use this chip with either 3V or 5V power and logic. It comes in a breadboard-friendly breakout and a spare stick of 0.1 male header for soldering on. We also have an I2C FRAM breakout board - which is large in size but slower (1MHz max I2C clock rate...
  • Adafruit Trellis Monochrome Driver Pcb For 4x4 Keypad & 3mm
    Precio:  $2,759.00

    Adafruit Trellis Monochrome Driver Pcb For 4x4 Keypad & 3mm

    -Titulo Original : Adafruit Trellis Monochrome Driver PCB for 4x4 Keypad & 3mm LEDs-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1616 // Stock Type: Components & Parts >> Switches // In Stock & Ready to Ship // This item is just for the Trellis driver PCB assembly: LEDs and buttons not included. Trellis is an open source backlight keypad driver system. It is easy to use, works with any 3mm LEDs and eight tiles can be tiled together on a shared I2C bus. This PCB is specially made to match the Adafruit 4x4 elastomer keypad. Each Trellis PCB has 4x4 pads and 4x4 matching spots for 3mm LEDs. The circuitry on-board handles the background key-presses and LED lighting for the 4x4 tile. However, it does not have any microcontroller or other 'brains' - an Arduino (or similar microcontroller) is required to control the Trellis to read the keypress data and let it know when to light up LEDs as desired. Each tile has an I2C-controlled LED sequencer and keypad reader already on it. The chip can control all 16 LEDs individually, turning them on or off. It cannot do grayscale or dimming. The same chip also reads any keypresses made with the rubber keypad. The connections are 'diode multiplexed' so you do not have to worry about ghosting when pressing multiple keys, each key is uniquely addressed. The tiles have 3 address jumpers. You can tile up to 8 PCBs together (for a total of 4x32 or 16x8=128 buttons/leds) on a single I2C bus, as long as each one has a unique address. All the tiles connect by the edges with solder, and share the same power, ground, interrupt, and i2c clock/data pins. So, you can easily set up to 128 LEDs and read up to 128 buttons using only 2 I2C wires! The tiles can be arranged in any configuration they want as long as each tile is connected to another with the 5 edge-fingers. Each LED is multiplexed with a constant-current driver, so you can mix and match any colors you like. You don't need it to be all blue, all red, etc. Mix it up! Any 3mm LED can be used, although we find that diffused LEDs with 250mcd+ brightness look best. This item is just for the Trellis ...

This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX9814, a specialty chip that is designed for amplifying electret microphones in situations where the loudness of the audio isn't predictable. This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, and even quiet, far-away sounds will be amplified. This amplifier is great for when you want to record or detect audio in a setting where levels change and you don't want to have to tweak the amplifier gain all the time. The chip at the heart of this amp is the MAX9814 , and has a few options you can configure with the breakout. The default 'max gain' is 60dB, but can be set to 40dB or 50dB by jumpering the Gain pin to VCC or ground. You can also change the Attack/Release ratio, from the default 1:4000 to 1:2000 or 1:500. The ouput from the amp is about 2Vpp max on a 1.25V DC bias, so it can be easily used with any Analog/Digital converter that is up to 3.3V input. If you want to pipe it into a Line Input, just use a 1-100uF blocking capacitor in series (100uF sounds best). For audio-reactive projects, we suggest using an FFT driver library (such as the one in this library) which can take the audio input and 'translate' it into frequencies. If you just need to keep track of audio levels, see our sound-level meter tutorial for Arduino Each order comes with one assembled and tested board, with electret mic pre-soldered on, and a small piece of header. Our tutorial will get you started with using and testing the microphone amplifier and you can check out our general-purpose mi...

    Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Se

    -Titulo Original : Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Sensor-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2651 // Stock Type: Sensors >> Barometric Pressure // In Stock & Ready to Ship // Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with  ±1 meter accuracy.The BMP280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C orSPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.Nice sensor right? So we made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry. We even wrote up a nice tutorial with wiring diagrams, schematics, libraries and examples to get you running in 10 minutes!

    Adafruit RF Development Tools Feather 32u4 RFM69HCW Packet R

    -Titulo Original : RF Development Tools Adafruit Feather 32u4 RFM69HCW Packet Radio - 868 / 915 MHz-Fabricante : ADAFRUIT-Descripcion Original: This is the Adafruit Feather 32u4 Radio (RFM69HCW) 900MHz - our take on an microcontroller packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather 32u4 with a 900 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GHz 802.15.4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi. We have other boards in the Feather family, check'em out here. This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. We also sell a 433MHz version of the same radio chipset and if you want much longer range, check out the LoRa 900MHz Feather At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as it's the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. 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...

    Adafruit Bluefruit Le Sniffer - Bluetooth Low Energy (ble 4

    -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.
