This is a WiFi relay module, including a removable ESP8266 module. You can control the functions of the relay over your WIFI network, or it can run in AP mode. A perfect solution for controlling all your household appliances, alarm control, pool pumps and gate motors.

Warning: if you are brand new to microcontroller programming, you will have a bit of a learning curve. Have a look at the documents below. Also, note that you will need an FTDI module or something similar to connect to this module to configure the Wifi network it should connect to or the mode it should operate in.

• Configurable baud rate
• On board ST-Micro CPU: STC15F104
• Relay rated for maximum 220V - 10A
• Input voltage 5V
