The ESP8266 single-channel relay development board is equipped with an ESP-1 2F WIFI module, all I/O ports are exported, and supports various power supply methods such as AC90-250V/DC7-12V/USB 5V. Suitable for ESP8266 secondary development and learning, smart home wireless control and other occasions.
1. Onboard mature and stable ESP-12F Wifi module, large capacity 4M Byte Flash
2. The I/O port and UART program download port of the WiFi module are all led out, which is convenient for secondary development
3. Onboard AC-DC power supply module, power supply mode supports AC90-250V/DC7-1 2V/USB5V
4. Onboard WiFi module RST reset button
5. ESP-12F supports the use of development tools such as Eclipse
6. Onboard 1 5V relay, output switch signal, suitable for controlling the working voltage
Load within AC 250V/DC 30V
7. Onboard power indicator, programmable LED and relay indicator
1.L, N: AC90-250V power supply
2.AC90-250V to DC5V switching power supply (when using AC power supply, please don’t touch it directly with your hands!!)
3.VCC, GND: DC7-12V power supply;
4.Micro USB: DC5V USB power supply;
Note: AC90-250V, DC7-12V, DC5V USB can choose one of three power supply modes.
5.6X6mm button: ESP8266 reset button;
6. UART program download port: ESP8266’s GND, RX, Tx, 5V are respectively connected to the external TL serial port module’s GND, TX, RX, 5V, 100 must be connected to GND when downloading, and then disconnect the I00 and GND after the download is completeconnection;
7. GPIO pin header leads to the port;
8. Relay output:
Normally closed, the relay is short-connected with COM before the pull-in, and hangs in the air after pull-in;
COM: public end;
NO: Normally open end, the relay is suspended before being closed, and shorted to COM after being closed.
9. Power indicator LED;
10. Programmable LED;
11. Relay indicator LED: lights up when it is closed.
