Adafruit GEMMA Wearable Platform v2

GEMMA is a tiny wearable platform built on a round 1.1 inch (2.8 cm) diameter board. The microcontroller at the heart of GEMMA is the Atmel Attiny85 8-bit MCU and is programmable with an Arduino IDE over USB.

This, the second generation of GEMMA, is physically and code-wise identical to the original but now has a Micro-B USB connector and an On-Off switch. It was designed mainly for wearable applications but its small size and low cost makes it great for a wide range of portable projects.

The Attiny85 processor has 8K of flash and 5 I/O pins, including analogue inputs and PWM outputs. There is a USB bootloader available from Adafruit.com but although you can program GEMMA using the Arduino IDE, it is not fully 100% Arduino compatible.
