Input and Output Interface
Five pinholes are reserved in the module. There are five signal pins, VCC, GND,
out, TX and Rx. The pin distance is 2.54mm. If you need to adjust the distance and delay
time online, you can rewrite the internal parameters through the communication between
TX, RX of UART with AT58MP1T1RS32A. The following table is the definition of each pin
