Limitations:
On the STM32H735G-DK board, SPI5 and UART7 signals are sharing the same IOs with SAI1. As a
consequence, when using SPI5 or UART7 signals to control a device connected to STMod+, the audio codec
cannot be used. Same, the user must make sure that nothing is connected on Pmod
™
(1,2,3,4 pins) and
ARDUINO
®
(D10, D11, D12, D13 pins) connectors.

P1 Pmod

connector
The standard 12-pin Pmod
™
connector is available on the STM32H735G-DK Discovery board to support low
frequency, low I/O pin count peripheral modules. The Pmod
™
interface which is implemented on
STM32H735IGK6U Discovery board is compatible with the Pmod
™
type 2A and 4A I/O signal assignment
convention.
