Simplified carrier board based upon TE0701


95 in stock


The Trenz Electronic TE0705 carrier board provides functionality for testing, evaluation and development purposes of company’s 4 x 5 cm SoMs (System on Module). The carrier board is equipped with a broad range of various components and connectors for different configuration setups and needs. On-module functional components and multipurpose I/Os of the SoM’s PL and PS logic are connected via board-to-board connectors to the carrier board components and connectors for easy user access.

Micro SD card socket is connected to the B2B connector through a Texas Instruments TXS02612 SDIO Port Expander for voltage translation. The Micro SD card has 3.3V signal voltage level while Xilinx Zynq MIO bank uses 1.8V for VCCIO.

Dual Channel USB to UART/FIFO: The TE0705 carrier board has on-board USB 2.0 high-speed to UART/FIFO IC FT2232H from FTDI. Channel A can be used as JTAG Interface (MPSSE) to program the System Controller CPLD. Channel B can be used as UART Interface routed to CPLD. There are also 6 additional bus lanes available for user-specific use.

There is also a 256-byte serial EEPROM connected to the FT2232H chip pre-programmed with license code to support Xilinx programming tools.

The baseboard TE0705 is a “downgraded” version from TE0701 and it provides low-cost connection and extension to Trenz Electronic modules with a standard footprint of 4 x 5 cm. As little as possible has been changed in functionality (except the functionality that was removed).


Do not access the FT2232H EEPROM using FTDI programming tools; doing so will erase normally invisible user EEPROM content and invalidate stored AMD/Xilinx JTAG license. Without this license, the on-board JTAG will not be accessible any more with any AMD/Xilinx tools. Software tools from the FTDI website do not warn or ask for confirmation before erasing user EEPROM content.
