Thunder Pack ARM micro-controller board

 Makers, developers and hobbyists searching for a self-contained ARM micro-controller board, small enough to fit in your pocket, the Thunder Pack might be with more investigation. Thunder Pack is a small ARM micro-controller board with built-in battery and power management. The original design was created to run on a single 18650 cell, but Jeremy, Thunder Pack’s designer, now has three boards that support similar but smaller rechargeable cells for projects that don’t need quite as much power. Jeremy explains a little more about the project.

“Why? I’ve built a lot of wearable lighting projects and got tired of wiring together the same 3 parts: arduino, charging controller & battery. They always felt janky and flat lipo batteries can explode if they get damaged (especially if you’re wearing it!!!) “

“I wanted something compact, rugged and could pump out enough current for a lot of blinkenlights without any additional parts. What I’ve ended up with is this little beast with 4 onboard PWM MOSFETs, each driving up to 2.3A per channel!!! Develop your project faster with onboard LEDs attached to each PWM output — so you can play without wiring anything up. It’s breadboard friendly, has 8 additional GPIOs (12 total) and a git repo with examples in Arduino, ChibiOS, libopencm3, and STM32Cube — choose your favorite flavor.”
