5 M0 Input(weak pull-up) With M1, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used).
6 M1 Input(weak pull-up) With M0, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not
7 RXD Input TTL UART input ,Connect to external TXD output pins; Can be configured as drain open circuit or pull up input, see parameter Settings
8 TXD Output TTL UART output, Connect to external RXD input pin; Can be configured as drain open circuit or push - pull output, see parameter Settings
9 AUX Output Used to indicate the working status of the module; The user wakes up the external MCU and outputs low level during self-test initialization; Can be configured as drain open output, or push-pull output, see parameter Settings (can be suspended)
