    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 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...

    -Titulo Original : Adafruit Pro Trinket LiIon/LiPoly Backpack Add-On-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2124 // Stock Type: Power >> LiIon & LiPoly >> Accessories // In Stock & Ready to Ship // If you have a Pro Trinket you probably know it's the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 boards together to make a charging system, this little PCB sits on top of the Pro Trinket and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket USB port is powered, the battery is recharged automatically. Unplug the USB port and the Pro Trinket will switch over to the rechargeable battery.Ideally, this backpack is for use with the 3.3V Pro Trinket, so that the battery voltage (3.7V-4.2V) will get regulated down to 3.3V on the Pro Trinket board. However, many times, you can run a 5V Pro Trinket + accessories off of the ~4V from the LiPoly battery with no problem. (Technically its overclocking but we've never seen that affect the Pro Trinket itself, AVRs are happy to overclock without complaint).Solder the backpack on with the extra long header so that it can still plug into a breadboard, or clip the long header leads short afterwards for a slim package. 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.If you want to add an On/Off switch, we also made that really easy. The two 0.1 holes with a box around them are the battery output line. Carefully cut the trace between them with a hobby knife and replace with two wires from a switch like this slide switch , or this pushbutton one , for example. 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.

    Adafruit 2488 Metro 328 With Headers - ATmega328

    -Titulo Original : Adafruit Metro 328 With Headers - ATmega328-Fabricante : Adafruit-Descripcion Original: Power the METRO with 7-9V polarity protected DC or the micro USB connector to any 5V USB source. The 2.1mm DC jack has an on/off switch next to it so you can turn off your setup easily. The METRO will automagically switch between USB and DC. // METRO has 19 GPIO pins, 6 of which are Analog in as well, and 2 of which are reserved for the USB-serial converter. There's also 6 PWMs available on 3 timers (1 x 16-bit, 2 x 8-bit). There's a hardware SPI port, hardware I2C port and hardware UART to USB. Logic level is 5V but by cutting and soldering closed a jumper, you can easily convert it to 3.3V logic // USB to Serial converter, there's a hardware USB to Serial converter that can be used by any computer to listen/send data to the METRO, and can also be used to launch and update code via the bootloader // Four indicator LEDs, on the front edge of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for the UART, and a red LED connected to pin PB5 // Arduino IDE compatible, you can use this with the Arduino IDE (both desktop and cloud version) by selecting 'Arduino UNO' in the Boards menu. // We sure love the ATmega328 here at Adafruit, and we use them a lot for our own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. This is the Adafruit METRO with headers. It comes with headers soldered on. It's a fully assembled and tested board with through-hole headers attached. If you don't want a Metro with the headers attached for super-slimness, check out our Metro without Headers. METRO is the culmination of years of playing with AVRs: we wanted to make a development board that is easy to use and is hacker friendly. At the heart is an ATmega328P, with 32KB of flash and 2KB of RAM, running at 16 MHz. It comes with the Optiboot bootloader already installed, and is Arduino IDE compatible...

    Adafruit Feather M4 Express - Featuring ATSAMD51 - ATSAMD51

    -Titulo Original : Adafruit Feather M4 Express - Featuring ATSAMD51 - ATSAMD51 Cortex M4-Fabricante : ADAFRUIT-Descripcion Original: 512KB Flash and 192KB RAM // ATSAMD51J19 // 120MHz Cortex M4 // It's what you've been waiting for, the Feather M4 Express featuring ATSAMD51. This Feather is fast like a swift, smart like an owl, strong like a ox-bird (it's half ox, half bird, OK?) This feather is powered by our new favorite chip, the ATSAMD51J19 - with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset. And best of all, it's a Feather - so you know it will work with all our FeatherWings! What a great way to quickly get up and running. The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE - and it's bonkers fast when you do, we are shipping it 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. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. When you're done, unplug the Feather and your code will go with you. The Feather M4 Express uses the extra space left over to add a Mini NeoPixel, 2 MB SPI Flash storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB...
