FLORA is Adafruit's fully-featured wearable electronics platform. It's a round, sewable, Arduino-compatible microcontroller designed to empower amazing wearables projects. The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up - all you need is a Mini-B USB cable, no additional purchases are needed! We have a modified version of the Arduino IDE so Mac & Windows users can get started fast - or for power-users we have instructions on how to modify an existing Arduino IDE install. The FLORA has USB HID support, so it can act like a mouse or keyboard to attach directly to computers.
