STeMCell STM32 Pro Micro Controller

The STeMCell is a powerful Pro Micro replacement based on a fast STM32F411 Arm chip with plenty of memory

Features

  • Pinout compatible with the classic Pro Micro with additional 5 I/O pins along the bottom edge
  • Powerful STM32F411 Arm microcontroller clocked at 100 MHz with 128 KB SRAM and 512 KB of flash
  • 21 GPIO pins (3.3 V logic instead of 5 V)
  • Only 4 mm thick thanks to a partially mid-mounted USB-C socket
  • Effortless drag & drop flashing (TinyUF2 bootloader)
  • Includes standard header pins (2x 12 pin)

Flashing QMK

QMK for any Pro Micro based keyboard can be built and flashed by simply adding an extra argument to the command line:

qmk flash -kb crkbd -km default -e CONVERT_TO=stemcell
