Interface Description:
VCC: power supply (5.0V)
RXD: The receiving pin of the module's own port (TTL level, not directly connected to RS232 level!) can be connected to the TXD of the MCU
TXD: The receiving pin of the module's own port (TTL level, not directly connected to RS232 level!) can be connected to the RXD of the MCU
GND: Ground
Pin function:
The pins that must be connected for normal communication:
1. USB interface: to connect to a computer or host computer, it must be connected. Turn the power selection switch to the V-USB side to get power from the USB.
2.TX A/B/C/D: Serial data transmission pin (refers to the module's own data outflow→, corresponding to the RX. data reception of the external device.)
3. RX A/B/C/D: Serial data receiving pin (refers to the module's own data input ←, corresponding to the external device's TX. data transmission.)
4. GND: power ground (GND must be connected and must not be wrongly connected, otherwise it may damage the device or serial port module)
