This header has a 'XMOD FTDI JTAG Adapter'-compatible pin-assignment, so the XMOD-FT2232H adapter-board TE0790 can be used in conjunction with the carried board to program the mounted SoM via USB interface.

Optional Pin-headers
The TEBA0841 base-board has place-holders with solder-pads to mount optional pin-headers capable to access the PL IO-bank pins of the mounted 4 x 5 SoM. With this user interfaces, a large quantity of IO's are also usable as LVDS-pairs and different VCCIO's are available to operate the IO's properly.
...
On the TEBA0841 carrier board the PL IO-bank's supply voltages of the 4x5 SoM (VCCIOA, VCCIOD; see 4x5 Module Integration Guide) are connected to the base-board VCCIO-voltage VCCIOA and VCCIOD, which are selectable between the supply-voltages 1.8V, 2.5V and 3.3V via jumper J26 and J27.

| Note |

Note: The corresponding PL IO-voltage supply voltages of the 4x5 SoM to the selectable base-board voltage VCCIOA and VCCIOD are depending on the mounted 4x5 SoM and varying in order of the used model. Refer to SoM's schematic to get information about the specific pin-assignment on module's B2B-connectors regarding PL IO-bank supply-voltages and to the 4x5 Module integration Guide for VCCIO voltage options. |
Following table describes how to configure the base-board supply-voltages by jumpers:
baseBase-board supply-voltagesSupply Voltages | VCCIOA | VCCIOD |
|---|---|---|
| 1.8V | J26:1-2 | J27:1-2 |
| 2.5V | J26:3-4 | J27:3-4 |
| 3.3V | J26:5-6 | J27:5-6 |
Table 6: Configuration of base-board supply-voltages via jumpers. Jumper-Notification: 'Jx: 1-2' means pins 1 and 2 are connected, 'Jx: 3-4' means pins 3 and 4 are connected, and so on.
| Note |
|---|
| It is recommended to set and measure the PL IO-bank supply-voltages before mounting of TE 4x5 module to avoid failures and damages to the functionality of the mounted SoM. |
