What do you get when you combine an Adafruit classic with geniuses at Arduino? The Arduino GEMMA! It's a tiny wearable platform board with a lot of might in a 1" diameter package. Powered by a Attiny85 and programmable with an Arduino IDE over USB, you'll be able to realize any wearable project.
This is a collaboration with Arduino.cc and Adafruit. This product is for US Sales only! Use Arduino IDE 1.6.4 or higher for Arduino Gemma support!
We worked with the folks over at Arduino to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your Adafruit Flora and you aren't willing to take apart the project you worked so hard to design. It's the Adafruit and Arduino lowest-cost sewable controller!
The Attiny85 is a great processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino (it uses 2 of the 5 I/O pins, leaving you with 3). In fact we even made some simple modifications to the Arduino IDE so that it works like a mini-Flora. Perfect for small & simple projects the Arduino GEMMA will be your go-to wearable electronics platform.
Even though you can program GEMMA using the Arduino IDE, it's not a fully 100% Arduino UNO-compatible. There are some things you trade off for such a small and low cost microcontroller!
Here are some useful specifications!
