Important General Note:

  • If some section is configurable and depends on Firmware, please refer to the addition page (for example CPLD). If not available, add note, that this part is configurable
  • Designate all graphics and pictures with a number and a description, Use "Scroll Title" macro

    • Use "Scroll Title" macro for pictures and table labels. Figure number must be set manually at the moment (automatically enumeration is planned by scrollPDF)
      • Figure template:

        Scroll Title
        anchorFigure_anchorname
        titleText


        Scroll Ignore

        Create DrawIO object here: Attention if you copy from other page, objects are only linked.

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.
