Expansion Connector

The phyCORE-AM62Px development kit provides a 60-pin 2.54mm expansion connector that brings out signals that were either not used elsewhere on the carrier board or were considered useful to have easy access too. For signals not used by either the SOM or the carrier board, they can be freely multiplexed to enable different functionality at the expansion connector. To learn more information about the phyCORE-AM62Px multiplexing, please refer to the Hardware Manual.
