6.17 Pmod connector P3
The standard 12-pin Pmod™ connector is available on the STM32H747I-DISCO Discovery
board to support low frequency, low I/O pin count peripheral modules. The Pmod™
interface, which has been implemented on the STM32H747I-DISCO Discovery board, is
compatible with the Pmod™ type 2A & 4A I/O signal assignment convention.
