The Trenz Electronic TE0791-01 is an adapter board for use with the XMOD TE0790 board. The adapter board provides several connector types to get access to the signals and interfaces of the XMOD board. As further option footprints are available for JST Wire-To-Board IDC connectors with two different pin-assignments.

2x6 Pin Header

The 2x6 pin header (2.54mm grid size, male) J2 of the TE0791 board have to be connected to the corresponding XMOD pin header on the TE0790 adapter board. The signal assignment of the pin header on the TE0790 adapter board depends on the configuration of its System Controller CPLD firmware.

The pin assignment on the TE0791 adapter board is the same as on the TE0790 XMOD board:

On the female 1-row 6-pin header J8 there (2.54mm grid size, female) J8 are the XMOD signals C, D, F and H available, which are the signals of . At standard System Controller CPLD firmware, this signals create the JTAG interface of the XMOD board with standard System Controller CPLD firmware:
