Wi-Fi Relay Module ESP8266

Simple WiFi relay module with ESP8266. It requires a power supply of 5 to 28V and can switch loads of up to 10A.

ESP8266 port mapping:
GPIO 02 – LED
GPIO 04 – Relay
GPIO 05 – Button

A serial connection is required for programming. The ESP8266 can be easily programmed using Arduino IDE, for example.

Any USB-UART will do. For example our FT232 compatible module, the CH340 adapter or the PL2303 cable.
