NodeMCU ESP8266 ESP-12E Dev Board with 1-Channel Relay
Price in Sri Lanka

This is an ESP8266 10A DC 7-30V Network Relay WIFI Module, which based on the ESP8266 and a 10A relay. It can connect by the server through TCP Client and also can control by the HTTP. With this module, you can upload your firmware than can maker more perfect IOT project you like. It is good for your smart home and IOT project with network control.

It also has a wide input voltage range(DC7V-DC30V), and input over-voltage protection, input with TVS, as long as the input voltage exceeds 33v, it will automatically protect. Similarly, the input current exceeds a certain value will turn on automatic protection.
The circuit board has an output status indicator and an input status indicator. It can be accessed through the TCP client-server control can also be controlled through the HTTP protocol, the control of diverse and easy to operate.

Features :

• With ESP8266 Wifi module,4-layers board design.
