STM32F4 Discovery board

Family: STM32 · Languages: Arduino C++

ST’s own STM32F407VG evaluation board — Cortex-M4 with FPU and a far wider pin map than the pill boards, which is the reason to choose it: the F407 brings out peripherals the 48-pin boards never expose.

It is the largest STM32 in the catalog by pin count, so it is also the one to place when a project has simply run out of pins elsewhere.

New STM32F4 Discovery project opens the editor with this board and a working blink sketch. STM32 boards need a paid plan — see plans.
