20 M0 (very weak pull-up)

In conjunction with M1, it determines the module's four operating modes (it cannot be left floating; if not in use, it can be grounded).

21 M1
(very weak pull-up)

In conjunction with M0, it determines the module's four operating modes (it cannot be left floating; if not in use, it can be grounded).

22 RXD input

TTL serial port , connected to the external TXD output pin;

23 TXD Output

TTL serial port output, connected to the external RXD  pin;

24 TO Output

Used to indicate the module's working status;

When the user wakes up the external MCU, it outputs a low level during the power-on self-test initialization period; (this level can be left floating).
