1
Pin No. Pin name Pin orientation Pin usage
1 GND - Module ground wire
2 GND - Module ground wire
3 GND - Module ground wire
4 GND - Module ground wire
5 M0 Input (very weak pull-up) Cooperate with M1 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded)
6 M1 Input (very weak pull-up) Cooperate with M0 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded)
7 RXD enter TTL serial port input, connected to the external TXD output pin;Can be configured as open-drain or pull-up input, see parameter settings for details.
8 TXD output TTL serial output, connected to external RXD input pin;Can be configured as open-drain or push-pull output, see parameter settings for details.
9 AUX output It is used to indicate the working status of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; it can be configured as open-drain output or push-pull output, see parameter settings for details. (can be left floating)
