STM32F4 Discovery

The board as it appears on the Velxio canvas, with its full pin map read live from the simulator (regenerated by scripts/gen-boards.mjs, so it always matches what you can wire).

About this board

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.
