6.16 STMod+ connector P2
The standard 20-pin STMod+ connector is available on STM32H747I-DISCO board to
increase compatibility with external boards and modules from the Ecosystem of
microcontrollers. By default, it is designed to support an ST dedicated Fanout board which
allows connecting different modules or board extensions from different manufacturers.
Fanout board also embeds a 3V3 regulator. For more detailed information, please refer to
ST Fanout board user manual and to relevant datasheets of associated modules.
For details about STMod+ interface, please refer to the STMod+ connector interface
specification.

That this connector shares many GPIOs with other functions on the board. For more
detailed information, refer to
Appendix B: STMod+ GPIO sharing and multiplexing.
In addition, to have a quick look at STMod+ GPIO sharing and multiplexing, and to get a
quick view on other Alternate functions available on its pins, please refer to
