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 is small (45mm diameter, weighing 4.4 grams) and has built-in USB support - all you need is a Mini-B USB cable, no additional purchases are needed! Adafruit provide a modified version of the Arduino IDE for Mac & Windows users.The FLORA also has USB HID support, so it can act like a mouse or keyboard to attach directly to computers.
FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is designed to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size.
FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control. Often FETs are not included in wearable board designs which leads to switch failure as small SMT switches are only rated for low current use. The FLORA has an onboard 3.3v 150mA voltage regulator with a protection diode and USB fuse so that the microcontroller voltage is consistent and can power common 3.3v modules and sensors.
FLORA is fabric friendly-- all the components on board are flush to the PCB and won't snag delicate garments.
