STMicroelectronics STM32 boards (netduino2, netduinoplus2, stm32vldiscovery)

The STM32 chips are a family of 32-bit ARM-based microcontroller by STMicroelectronics.

The STM32F1 series is based on ARM Cortex-M3 core. The following machines are based on this chip :

  • stm32vldiscovery STM32VLDISCOVERY board with STM32F100RBT6 microcontroller

The STM32F2 series is based on ARM Cortex-M3 core. The following machines are based on this chip :

  • netduino2 Netduino 2 board with STM32F205RFT6 microcontroller

The STM32F4 series is based on ARM Cortex-M4F core, as well as the STM32L4 ultra-low-power series. The STM32F4 series is pin-to-pin compatible with STM32F2 series. The following machines are based on this ARM Cortex-M4F chip :

  • netduinoplus2 Netduino Plus 2 board with STM32F405RGT6 microcontroller

  • olimex-stm32-h405 Olimex STM32 H405 board with STM32F405RGT6 microcontroller

  • b-l475e-iot01a B-L475E-IOT01A IoT Node board with STM32L475VG microcontroller

There are many other STM32 series that are currently not supported by QEMU.
