FLORA is Adafruit's fully-featured wearable electronics platform. It's a round, sewable, Arduino-compatible microcontroller designed to empower amazing wearables projects. FLORA is well supported by Adafruit with plenty of tutorials and projects in the Adafruit Learning System. Check out dozens of FLORA tutorials on the Adafruit Learning System, with more added all the time!

The Flora microcontroller is small, just 1.75″ diameter and weighing 4.4 grams – so it is pretty easy to fit just about anywhere. FLORA has built-in USB support – all you need is a USB micro cable, no additional purchases required to get it up and running! The FLORA also has USB HID support, so it can act like a mouse or keyboard to attach directly to computers.

Powering the Flora V3 by battery is simple: there is an onboard polarized 2 pin JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC. It can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of basically any size. The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric. We suggest one of our micro-lipo chargers if you want to use LiPo batteries with FLORA.

FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control, so you can power quite a bit without burning out your switch. The FLORA has an onboard 3.3v 250mA regulator with a protection diode and USB fuse so that the microcontroller voltage is consistent and can power common 3.3v modules and sensors.

Adafruit has spent a lot of time on the power supply because the FLORA power system is specifically designed to allow easy control and power of a large quantity of addressable NeoPixels. Flora can easily drive 50 pixels directly from the onboard power supply, or up to 500 with the pixels externally powered by a separate 5V supply.
