How to Use
1. Programming Port: ESP8266's GND, RX, TX, 5V are respectively connected to the GND, TX, RX, 5V of the external TTL serial port module. IO needs to be connected to GND when downloading, and then disconnect the connection between I00 and GND after the download is complete.
2. Relay Output:
NC: Normally closed, the relay is short connected with COM before it is closed, and it is suspended after it is closed.
COM: Common terminal.
NO: Normally open end, the relay is suspended before being closed, and shorted to COM after being closed.
