A kick-ass microcontroller board with everything you need in a compact package that fits in your pocket. Integrated battery, power management system, Arm microcontroller, USB bootloader, 4 high-power PWM outputs, and 12 GPIOs.
Why? After years of wiring together portable LED controllers that all consisted of a lithum batter, charge controller, 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! This board has everything I need with room to expand.

This is the latest stable release of CircuitPython that will work with the Thunderpack.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the Thunderpack.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
