Overview

A kick-ass microcontroller board with everything you need in a tiny package that fits in your pocket. Integrated battery & power management system, fast ARM microcontroller, USB bootloader, 4 high-power PWM outputs, 12 GPIOs, satisfying pushbutton switch, and more.

After years of wiring together portable LED controllers that all consisted of a lithium battery, charge controller, shitty slide power switch, and an Arduino nano (or similar), I wanted something better. I always found those versions to be janky and fragile -- not to mention concerned that damaging the pouch cell battery might make it explode in my pocket! This board has everything I need with room to expand.
