The Attiny85 is a fun 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 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-compatible. There are some things you trade off for such a small and low cost microcontroller! GEMMA does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data Some computers’ USB v3 ports don’t recognize the GEMMAs bootloader. Simply use a USB v2 port or a USB hub in between We do not have full Windows 8 driver compatibility tested. At this time we only have it working with Mac, Linux or Windows 7/XP
Easy-to-sew or solder pads for embedding in your wearable project
Low cost enough, you can use one for every weekend project
Ultra low power, draws only 9 mA while running
