3.11. UART Interfaces

The module provides two UART interfaces: the main UART interface and the debug UART interface.

Their features are shown below:

⚫

The main UART interface supports 4800 bps, 9600 bps, 19200 bps, 38400 bps, 57600 bps, 115200

bps, 230400 bps, 460800 bps and 921600 bps baud rates, and the default baud rate is 115200 bps.

This interface is used for data transmission and AT command communication.

⚫

The debug UART interface supports 115200 bps baud rate. It is used for Linux console and log

output.

The following tables show the pin definition.
