Onboard WiFi module RST reset button and a programmable button; 5. ESP-12F supports the use of development tools such as Eclipse\/Arduino IDE, and provides reference programs under the Arduino development environment; 6. Onboard 2 5V\/30A relays, output switch signals, suitable for controlling loads whose working voltage is within AC 250V\/DC30V; 7. On-board power indicator, relay indicator and 1 programmable LED. 3. Hardware introduction and description Board size: 83*68mm Weight: 85g 4. Interface introduction Programming 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, and then disconnect the connection between IO0 and GND after the download is complete; Relay output: NC: 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. 5.
