Overview
The Trenz Electronic TE0703 Carrier Board is a base-board for 4x5 SoMs, which exposes the MIO- and the PS/PL-pins of the SoM to accessible connectors and provides a whole range of on-board-components to test and evaluate Trenz Electronic 4x5 SoMs.
See page "4 x 5 cm carriers" to get information about the SoMs supported by the TE0703 Carrier Board.

Interfaces and Pins
Board to Board (B2B) I/O's
For detailed information about the B2B pin out, please refer to the Master Pinout Table.
Micro SD Card Socket
Micro SD Card socket is not directly wired to the B2B connector pins, but through a Texas Instruments TXS02612 SDIO port expander, which is needed for voltage translation due to the different voltage levels of the Micro SD Card and MIO bank 501 of the Xilinx Zynq 7000 chip. The Micro SD Card has 3.3 V signalling, but the MIO Bank 501 on the Xilinx Zynq 7000 chip is set to 1.8 V. !!! (card detect signal...)
Dual channel USB UART/FIFO
TE0703 has on-board USB 2.0 High Speed UART/FIFO FT2232HQ from FTDI. Channel A can only be used in simple UART mode, Channel B can be used as UART, FIFO, JTAG (MPSSE) or High Speed Serial modes. An standard 256 Byte EEPROM to store custom Configuration settings for FT2232H is available. EEPROM settings can be changed using FTDI provided tools that can be downloaded from FTDI website. See FTDI website for more information.
Ethernet
On-board ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LED's are all routed to CPLD Bank 1.
USB Interface
TE0703 board has two physical USB sockets:
- J4 as mini USB type B socket wired to on-board FTDI FT2232H chip.
- J6 as USB type A wired to B2B connector JM3 (there is usually something like SMSC USB3320 or similar USB transceiver on the module).
JTAG Interface
JTAG access to the CPLD and Xilinx Zynq chip is provided via Mini-USB JTAG Interface (FTDI FT2232H) and controlled by DIP switch S2-3.
LED's
There are four LED's onboard:
| LED | Color | Description |
|---|---|---|
| D1 | Red | FTDI UART receive activity |
| D2 | Green | FTDI UART transmit activity |
| D3 | Red | FL_0 |
| D4 | Green | FL_1 |
LED's D3 and D4 are connected to the 4x5 B2B connector pins. Those LEDs can be controlled by FPGA Module
