Description
The STeMCell is the next generation of STM32 based controllers. If your keyboard is designed for pro-micro style controllers, this will boost it to new heights. The STeMCell is lightning fast with a clockspeed of 100MHz (compared to 8MHz for most other controllers) and with 512kb of flash memory you won't have to trim down your QMK firmware to fit your controller anymore either.
Quick specs:
- STM32F411CEU6 microcontroller
- 100MHz clockspeed
- 512kB Flash Memory (storage)
- 128kB RAM
- Mid-mount low profile USB C connector
- Supported by QMK and ZMK
- ProMicro compatible + 5 extra inputs / outputs (similar to Elite-C)
- Suitable for use with header pins as well as PCB mount via castellated pads
