Set Up a USB-to-UART Module

The Trion T120 BGA324 Development Board does not have a USB-to-UART converter. Therefore, you need to use a separate USB-to-UART converter module. A number of modules are available from various vendors; any USB-to-UART module should work.

Figure 1. Connect the UART Module to I/O header J12
  1. Connect the UART’s RX, TX and ground pins to the Trion T120 BGA324 Development Board using:
    • RX – GPIOT_RXP20, which is labeled as 1 on header J12
    • TX – GPIOT_RXN20, which is labeled as 7 on header J12
    • Ground – Ground, connect to one of the GND pins on header J12
  2. Plug the UART module into a USB port on your computer. The driver should install automatically if needed.
