What is the pin pitch of STM32H747I-DISCO connectors.

Hi All,

What is the pin pitch of each connector on STM32H747I-DISCO kit bellow. Pin pitch means the distance measured from the center of one pin to the center of the next pin.

・STMod+ connector

・Pmod connector

・ARDUINO connector

Thanks in advance.

Hello,

・STMod+ connector => 2mm

・Pmod connector => 2.54mm

・ARDUINO connector => 2.54mm for the shortest distance. But the 4 connectors implementation is exotic. Please check the CAD files here:

@Mike_ST The UM refers to these as "standard" connectors. It would be helpful if it gave links to the specifications.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

More infos on those connectors:

PMOD specification

It would be good if that were included in the documentation of all ST boards which use these interfaces.
