Stemcell

Footprint: Pro Micro
Connectivity: wired
Chip: STM32
Firmware: QMK

166 designs socket a Pro Micro-shaped controller.

You can build these with it

This board fits the socket these 33 designs take, and runs firmware each of them ships.

Same socket, firmware not ready

133 designs take the same connector. Nothing says Stemcell cannot drive them — only that no source we read says it does, so treat each one as a porting job rather than a purchase.
