Description:
DC5-80V power supply ESP8266 relay module is suitable for ESP8266 development and learning, smart home wireless control and other occasions.
Interface Description
1. VCC, GND: DC8-8OV power supply
2.MICRO USB: DC5V USB power supply
Note: You can choose one of the three power supply modes of DC8-80V/DC5v USB/pin 5V
3.6X6MM button: ESP8266 reset button
4. UART program download port: GND, RX, TX, 5V of ESP8266 are respectively connected to external TTL serial port module
GND, TX, RX, 5V, IO0 needs to be connected to GND when downloading, and then disconnect IO0 and
Connection between GND
5. GPIO pin header leads to the port
6. Relay output
NC: Normally closed, the relay is short-connected with COM before it is closed, and it is suspended after being closed;
COM: public end;
NO: Normally open end, the relay is suspended before being closed, and shorted to COM after being closed.
7 Power indicator LED
8 Programmable LED: use GPIO16 to control;
9 Relay indicator LED: lights up when closed
