19The STM32F4 series is based on ARM Cortex-M4F core. This series is pin-to-pin
20compatible with STM32F2 series. The following machines are based on this chip :
21
22- ``netduinoplus2``     Netduino Plus 2 board with STM32F405RGT6 microcontroller
23- ``olimex-stm32-h405`` Olimex STM32 H405 board with STM32F405RGT6 microcontroller
