ESP8266 ESP-12F Relay Module AC 90 -250V DC 12V WIFI Relay Switch Board Wireless Remote Control for Arduino Smart Home Description: The ESP8266 single-channel relay development board is equipped with ESP-12F WiFi module, all I/O ports are led out, and it supports AC90-250V/DC7-12V/USB 5V and other power supply methods. Provide Arduino development environment reference code, suitable for ESP8266 secondary development learning, smart home wireless control and other occasions.   Feature: Onboard mature and stable ESP-12F WiFi module, large capacity 4M Byte Flash The I/O port and UART program download port of the WiFi module are all led out to facilitate secondary development Onboard AC-DC switching power supply module, power supply mode supports AC 90-250V / DC7-12V / USB5V Onboard WiFi module RST reset button ESP-12F supports the use of Eclipse/Arduino IDE and other development tools, and provides reference programs under the Arduino development environment Onboard 1 5V relay, output switch signal, suitable for controlling load with working voltage within AC 250V/DC30V On-board power indicator, 1 programmable LED and relay indicator   Interface introduction: 1. L, N: AC 90-250V power supply 2. AC 90-250V to DC 5V switching power supply (do not touch it directly with your hands when using AC power supply!!!) 3. VCC, GND: DC 7-12V power supply 4 Micro USB: DC5 V USB power supply Note: AC 90-250V, DC 7-12V, DC 5V USB can choose one of the 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 GND, TX, RX, 5V of the external TTL serial port module. IO0 needs to be connected to GND when downloading. After the download is complete, disconnect the connection between IO0 and GND 7. GPIO pin header lead out port 8. 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: public NO: Normally open end, the relay is suspended before closing, and shorted to COM after closing 9. Power indicator LED 10. Programmable LED 11. Relay indicator LED: lights up when closed   Package Included: 1* ESP8266 ESP-12F Relay Module AC 90 -250V DC 12V WIFI Relay Switch Board Wireless Remote Control for Arduino Smart Home
