This is a prototype I've been working on for a couple months now. With all the same features as the main ThunderPack board, but much, much smaller! (40mm x 19 mm)
It also has an on-board 16Mb flash chip and a DotStar status LED. (both of these are also getting added to the next version of the standard ThunderPack board).
Due to it's size, I did have to drop a couple things:
- Individual physical LEDs on the PWM outputs.
- USB ESD protection.
- On-board battery.
This board is perfect for wearable applications that need to be lightweight.
I've been building this prototype into a leather choker, similar to this Adafruit's Tutorial, for a friend. However, in my version the board is truly integrated with the choker with the switch poking through a slot in the leather and the LEDs mounted to a custom flex PCB from OSH park. I'll post pics and more info soon.
