Micro SD card socket is connected to the B2B connector through a Texas Instruments TXS02612 SDIO Port Expander port expander for voltage translation. The Micro SD card has 3.3V signal voltage level while most 4x5 modules use 1.8V for the SD card Interfaceinterface.
USB JTAG and UART
TE0703 has on-board USB JTAG and UART solution based on UART/FIFO controller from FTDI. FTDI EEPROM is pregrammed pre-programmed with license ID code to support Xilinx programming tools.
| Warning |
|---|
Do not access the FT2232H EEPROM using FTDI programming tools, doing so would erase the user EEPROM content and those invalidate the license. |
...
By careless use of FTDI software tools, it is possible to erase content of the 256-byte user EEPROM without confirmation. As a consequence, user loses the Digilent license stored in the EEPROM. |
Ethernet
On-board Ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LEDs PHY_LED1 and PHY_LED2 are both routed to System Controller CPLD bank 1.

Power
Power supply with minimum current capability of 3A for system startup is recommended.
Power Supply
TE0703 needs one single Single power supply with nominal minimum current capability of 3A at 5V for system startup is recommended.
