Functions of the pins:

• VCC: Power supply (3.3-5V)
• GND: connect Mass
• TXD: module serial port transmission pin (TTL level, cannot be directly connected to RS232 level), can be connected to the microcontroller’s RXD
• RXD: serial port of the pin receiving port (TTL level, can not be directly connected to RS232 level), can be connected to the TXD of single chip microcomputer
• PPX: pulse output angle
