Interface description

The GND, RX, TX, 5V of ESP8266 are connected to the GND, TX, RX, 5V of the external TTL serial port module respectively. IO0 should be connected to the GND when downloading, and the connection between IO0 and GND should be disconnected after downloading.

Relay output:

NC: Normally closed end, the relay is short-connected with COM before suction, suspended after suction;

COM: public terminal;

NO: usually start, the relay is suspended before suction, and shorted with COM after suction. This section describes GPIO outgoing ports
