On-board I2C bus is accaessable with the following pins:
| SDA | SCL | Notes |
|---|---|---|
| J1-144 | J1-142 | B2B |
| J6-7 | J6-5 | In-Circuit Programming |
| J21-10, J21-4 | J21-9, J21-3 | Pmod |
Table 8: I2C pins.
There are no I2C devices on the base board. Pullup resistors have to be provided by the module.

Pmods
The GPIOs of the 10 Pmods (J10 to J17, J20, J21) are connected with 100 Ohm differential routing to the B2B connector.J21 is a pure I2C compatible Pmod, without additional signals. The other 9 are GPIO Pmods where despite J20 all others can be used as dual Pmods. By default VCCIO_35 is connected with a 0 Ohm resistor to 3.3V. De-soldering this resistor and using pinheader J19 instead, the variable bank power VCCIO_35 for the Pmods J10, J11, J12, J13, J14, J16 can be selected.

USB to JTAG/UART bridge
The TEB0724 carrier board has on-board microUSB 2.0 (J4) high-speed to UART/FIFO IC FT2232H (U1) from FTDI. Channel A can be used as JTAG Interface (MPSSE) to program on module JTAG devices. Channel B can be used as UART Interface routed to via a level shifter to the 1.8V section of the B2B connector, usually connected to the PS of the SoM. There is also a 256-byte serial EEPROM connected to the FT2232H chip pre-programmed with license code to support Xilinx programming tools.
| Warning |
|---|
Do not access the FT2232H EEPROM using FTDI programming tools, doing so will erase normally invisible user EEPROM content and invalidate stored Xilinx JTAG license. Without this license the on-board JTAG will not be accessible any more with any Xilinx tools. Software tools from FTDI website do not warn or ask for confirmation before erasing user EEPROM content. |
CAN Screw Terminal
The CAN bus is routed to screw terminal J2.
| PIN | Signal | B2B |
|---|---|---|
| J2-1 | CAN0_N | J1-1 |
| J2-2 | GND | |
| J2-3 | CAN0_P | J1-3 |
Table 9: CAN bus connection.
Proper termination of the can bus can be set via jumpers on J22 according to the device position on the bus. Jumpers on J22-1 to J22-3 and J22-2 to J22-4 connect proper split termination resistors to the CAN bus.
Oscillators
The module has the following reference clock signals provided by on-board oscillators:
