  • Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3
    Precio:  $3,559.00

    Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3

    -Titulo Original : Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3G4200 Upgrade - L3GD20H [ADA1032]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1032 // Stock Type: Sensors >> Motion // In Stock & Ready to Ship // A gyroscope is a type of sensor that can sense twisting and turning motions. Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is - you can tell how an object is moving!) As these sensors become more popular and easier to manufacture, the prices for them have dropped to the point where you can easily afford a triple-axis gyro! Only a decade ago, this space-tech sensor would have been hundreds of dollars. This breakout board is based around the latest gyro technology, the L3GD20H from STMicro . It's the upgrade to the L3G4200 ( see this app note on what to look for if upgrading an existing design to the L3GD20 ) with three full axes of sensing. The chip can be set to ±250, ±500, or ±2000 degree-per-second scale for a large range of sensitivity. There's also built in high and low pass sensing to make data processing easier. The chip supports both I2C and SPI so you can interface with any microcontroller easily. Since this chip is a 3.3V max device, but many of our customers want to use it with an Arduino, we soldered it to a breakout board with level shifting circuitry so you can use the I2C or SPI interface safely using a 5V interface device. We also place a 3.3V regulator on there so you can power it from 5V. Since we expect people will want to attach it firmly to their project, the PCB comes with four 2.1mm mounting holes. Use #2-56 imperial or M2 screws screws. Getting started is easy - simply connect SDA to your Arduino I2C data pin (On the UNO this is A4), SCL to I2C clock (Uno: A5), GND to ground, and Vin to 3 or 5VDC. Then install and run our easy to use Arduino library, which will print out the XYZ sensor data to the serial terminal. Our library also supports SPI on any 4 digital I/O pins, see the example for wiring...
  • Adafruit INA169 Analog DC Current Sensor Breakout - 60V 5A M
    Precio:  $3,299.00

    Adafruit INA169 Analog DC Current Sensor Breakout - 60V 5A M

    -Titulo Original : Adafruit INA169 Analog DC Current Sensor Breakout - 60V 5A Max-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1164 // Stock Type: Breakout Boards >> Batteries/Power // In Stock & Ready to Ship // This breakout board will solve all your current-monitoring problems. Instead of struggling with a multimeter, you can just use the handy INA169 chip on this breakout to both measure both the DC current draw and have a handy analog output that is with respect to ground. The analog output makes this an ideal breakout for feedback-loop control. Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter - it can handle high side current measuring, up to +60VDC! A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. The resistor is rated for 2W continuous so you can measure up to +5A continuous. The output is a current that is drawn through the on-board 10K resistor so that the output voltage is 1V per Amp. So for 2A draw, the output will be 2V. You can change out the load resistor to be larger or smaller by cutting the traces next to it and soldering a thru hole resistor over. If you solder in a 20K resistor you'll get 2V per Amp, with a 5K resistor, 0.5V per Amp. We include a 5-pin header (so you can easily attach this sensor to a breadboard) as well as a 3.5mm terminal plug so you can easily attach and detach your load. Usage is simple. Power the sensor with 2.7-60V, and connect V+ to the high side of your power supply, then connect V- to your grounded load. Then use a multimeter to measure the voltage output, that's it...
  • Adafruit Electret Microphone Amplifier - Max9814 With Auto
    Precio:  $2,569.00

    Adafruit Electret Microphone Amplifier - Max9814 With Auto

    -Titulo Original : Adafruit Electret Microphone Amplifier - MAX9814 with Auto Gain Control [ADA1713]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1713 // Stock Type: Sensors >> Sound/Noise // In Stock & Ready to Ship // Color: Add an ear to your project with this well-designed electret microphone amplifier with AGC. 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 Liquid Crystal Light Valve - LCD Controllable Black

    -Titulo Original : Liquid Crystal Light Valve - LCD Controllable Black-Out Panel-Fabricante : ADAFRUIT-Descripcion Original: Outline size: 96.5 x 38.0 x 2.0 mm // View area: 88.5 x 34.5 mm // Driving voltage: 5.0V // LCD type: TN, transmissive, positive // Operating temperature: -10° to 60° // What do you get when you power a layer of liquid crystal material sandwiched between two sheets of glass? A Liquid Crystal Light Valve (a.k.a a LCD Controllable Black-out Panel)! They're often used for electric welding helmets because they can protect the welder's eyes from the bright sparks. Or – if you aren't a welder – they can be used to provide a reveal effect for your project, as you can control the opaqueness of the LCD. A Liquid Crystal Light Valve (LCLV) is a device that uses the properties of liquid crystals to control the level of illumination passing through an optical system. It's basically what goes on in your LCD monitor/TV/projector etc, but for each individual pixels. In this product, we have one huge LCD piece, which will filter what you see through it. Normally, its a tinted gray color (because the light around us is not polarized, it is not completely clear). There are two sets of electrodes, on the left and right. The two pins closest to each other (on the edges) are the same electrode, and the LCD is symmetric so you can use either one as positive/negative. By changing the voltage applied, it will block light more and more. Starting at about 1.0VDC the glass will start darkening. At about 4.0V the glass will be opaque. 5V is the max recommended voltage. In between you will get darker shades. Note that it is not capable of blocking 100% of light, but it looks like it blocks at least 95%. If you put a bright light behind it, you will see some light shine through! Almost no current is used and one the LCD, once activated with a voltage, will stay at that darkness level even if the voltage is removed. So, if you want to have it turn on and off, you'll need to drive it with a 0V signal to 'open' it up, or connect a draining resistor between the two pins to leak the voltage off when not powered...

    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...

Simply drill a 16mm hole into any material up to 1/2 thick and you can fit these in place, there's even a rubber gasket to keep water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a green plastic LED ring. On the back there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the green LED ring (+ and -). Connect 3 to 6V to the LED to have it light up nicely, there's a built in resistor! If you want to use this with a higher voltage, say 12V or 24V, simply add a 470 ohm resistor in series with the LED connection to keep the LED current at around 20mA. This button is an on/off switch button, when you press it the 'normally-open' contact shorts to the common contact and the button stays 'pressed'. When you press it a second time, the button springs open, and the contacts open up again. The switch and LED are separated, so you could wire it to turn on when pressed or vice versa or whatever you wish! Check the tech details for information...

    Adafruit Micro Lipo - USB LiIon/LiPoly Charger [ADA1304]

    -Titulo Original : Adafruit Micro Lipo - USB LiIon/LiPoly Charger [ADA1304]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1304 // Stock Type: Power >> LiIon & LiPoly >> Chargers // In Stock & Ready to Ship // Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use. Simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the back, for when you'll only be charging batteries with 500mAh size or larger. For use with Adafruit LiPoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.Comes assembled and tested with a free bonus JST cable!5V input via PCB-style USB connectorFor charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)100mA charge current, adjustable to 500mA by soldering a jumper closedFree 2-pin JST cable included!The MicroLipo charger can get hot during charging. Grab it by the sides and unplug then let cool before removing the battery - take care not to touch the components during charging! Batteries not included.

    Adafruit Usb To 2.1mm Dc Booster Cable - 12v [ada2778]

    -Titulo Original : Adafruit USB to 2.1mm DC Booster Cable - 12V [ADA2778]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2778 // Stock Type: Cables >> USB Cables // In Stock & Ready to Ship // This cable is kinda fascinating - it has an integrated boost converter, so you can plug it into any USB port (from a computer, battery pack, etc) and it will give you a higher DC voltage! It's a handy way to power 12V powered devices with a center-positive 2.1mm DC barrel jack from a USB port. We also have a version that provides 9V , and if you just need a passthough cable, here's one for 5VDC .These are rated at 500mA output, but you can go a little higher, we pulled 700mA and we got a little voltage droop but it worked fine. Probably best not to draw 700mA continuously though!Here's our measurements for various current draws when we set our bench supply to provide a steady 5V voltage50mA (12.4V output), 150mA,  83% efficiency100ma (12.4V), 290mA in, 86% efficiency200ma (12.3V): 570mA in, 86% efficiency300ma (12.2V): 870mA in, 84% efficiency500ma (12.1V): 1500mA in, 81% efficiency700ma (11.4V): 2140mA in, 75% efficiencySo, overall there's a 85% efficiency at low current draw that drops do about 80% at high current use. There's also a 3 mA quiescent current. Note that often times the USB port voltage can droop too, and in addition you may have power losses with any thin or low quality cables with high resistivity...

This needle set is the only one you'll need for any sort of hand sewing, especially using our conductive thread and wearable electronics parts. Each pack contains 20 gold-eye sharps, with eye sizes ranging from #3 (1.75 long) to #9 (1.35 long). The two #3's (the largest) are too large to pass through the sewable coin cell holder but otherwise are easy to use and thread. The four #9's (the smallest) are a little difficult to thread so you may not want to use them with our conductive thread - they'll be easier to use with normal thread however. The remaining 14 needles are perfect for use with our 2-ply stainless conductive thread , 3-ply stainless conductive thread or stainless conductive thin yarn ...
