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.
- Xmod form-factor
- size: 20 x 25 mm
- M3 mounting hole
- Different connector types available
- 2x6 PMOD connector
- JTAG 1-row pin header female
- 2x optional JST Wire-To-Board 6-pin IDC connector
- 2x optional JST Wire-To-Board 10-pin IDC connector
- IDC connectors with different pin-assignment each

Signals, Interfaces and Pins
2x6 Pin Header
The 2x6 pin header (2.54mm grid size, male) J2 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 its System Controller CPLD firmware.
The pin assignment on the adapter board is the same as on the TE0790 XMOD board:
|Signal||J2 Pin Name||J2 Pin Name||Signal|
|User Defined||C||A||User Defined|
|User Defined||D||B||User Defined|
|User Defined||F||E||User Defined|
|User Defined||H||G||User Defined / Button (Reset_n)|

1x6 Pin Header
On the female 1-row 6-pin header J8 there are the XMOD signals C, D, F and H available, which are the signals of the JTAG interface of the XMOD board with standard System Controller CPLD firmware:
|J8 Pin Number||J8 Pin Name||Signal||Note|
|1||VIO||VCCIO||depends on TE0790 voltage settings|

2x6 PMOD Header
On the 2x6 PMOD header J1 there are the all XMOD signals A - H available. The pin- and signal-assignment with standard System Controller CPLD firmware of the XMOD board are as follows:
|Note||Signal||J1 Pin Name||J1 Pin Number||J1 Pin Number||J1 Pin Name||Signal||Note|
|TCK (output from adapter)||C||A||UART TXD (output from adapter)|
|TDO (input to adapter)||up||D||B||up||UART RXD (input to adapter)|
|TDI (output from adapter)||F||E||down||LED|
|TMS (output from adapter)||H||G||up||Button (Reset_n)|
