How can I connect pins for WBR3 module flashing and authorization?

Last Updated on2022-12-05 07:23:14
To flash the firmware to the WBR3 module, you need to connect the 3.3V, GND, Log Tx, Log Rx, A0, and A13 (silkscreen: Rx) pins. During flashing, the A0 and A13 (Rx) pins need to be pulled up to 3.3V. After the firmware is flashed, the A0 and A13 (Rx) pins must be pulled down. Otherwise, the module cannot be started.
