Expansion Connector
===================

The Expansion Connector X28 allows access to many additional interfaces and is compatible with the PHYTEC Expansion Board (PCM-957). This expansion option was provided as a way to prototype custom solutions and test extended functionality with the phyCORE-AM57x carrier board. Standard interfaces such as UART, I2C, SPI, and various GPIO are made available here. To learn more information about this expansion, please see section 35 in the `Hardware Manual <https://www.phytec.com/product/phycore-am57x/#section-hardware-documentation>`_.
