Microcontrollers made by ST. The development boards are called Nucleo and are compatible with various Arduino shields. Many STM32 chips can run with the Espruino environment.
We have a couple different boards from the Microcontroller Hacking Night in the electronics room to play around with:
- 2x STM32F401
- 1x STM32L496
- 2x Dual DC motor driver expansion board (STSPIN240)
- 2x Motion MEMS and environmental expansion board
