STM32MP157F-DK2

The STM32MP157F-DK2 is a development board starring the STM32MP157F system on a chip and a ton of peripherals.

This board is a newer revision of the STM32MP157C-DK2 and as far as I can tell all STM32MP157C-DK2 hardware documentation applies to the STM32MP157F-DK2.

Almost all you need to know about this board and its chips is available without signing any kind of NDA or jumping through hoops. Very very convenient.
