ESP-12F supports the use of development tools such as ECLIPSE/ARDUINO IDE, and provides ARDUINO Reference program in the development environment; 6. Onboard 4 5V relays, output switch signal, suitable for controlling the working voltage of AC Load within 250V/Dc30V; 7. On-board power indicator, 1 programmable LED and relay indicator. Dimensions : Interface Description Burning port. ESP8266 GND, RX, TX, 5V are connected to the external TTL serial module GND, TX, RX, 5V, IO0 and GND need to be connected to the download, download is complete and then disconnect the connection between IO0 and GND; relay outputs: NC: Normally Closed, shorted before the relay is absorbed with the COM, after the absorption of the empty; COM: Common; NO: Normally Open, the relay is shorted with the COM before the absorption. NC: Normally closed terminal, shorted to COM before the relay is engaged, shorted to COM after the relay is engaged. Package Include: 1x AC/DC ESP8266 WIFI 4 Channels Relay Module ESP-12F Development Board ESP8266 Wireless WIFI 4CH Relay Module Development Board AC/DC Power Supply USA Description Function pending : 1.
