2.7 USB Connector

The xWRL6844EVM has two micro USB connectors. These connectors are for xds110 and FTDI interface connectivity. These connectors can also be used to provide 5V power supply input to the EVM.

FTDI Interface: Micro USB Connector J10 provides access to the xWL6844 device's UART-A, SPI, I2C, RS232/UART-B, SOP and Reset signals

XDS Interface:Micro USB connector J5 provides access to the xWL6844 device's I2C, JTAG, UART_A, RS232/UART-B signals. This is the UART interface used to flash the binary to the onboard serial flash and for running Out-of-box (OOB) demo.
