Overview
The Trenz Electronic TEB0728 Carrier Board provides functionalities for testing, evaluation and development purposes of company's 6 x 6 cm SoMs. The Carrier Board is equipped with various components and connectors for different configuration setups and needs. The interfaces of the SoM's functional units and PL I/O-banks are connected via board-to-board connectors to the Carrier Board's components and connectors for easy user access.
See "6 x 6 SoM Carriers" page for more information about supported 6 x 6 cm SoMs.
Refer to http://trenz.org/TEB0728-info for the current online version of this manual and other available documentation.
