ESP8266 Wireless Single Relay Breakout Board

This is a neatly designed board that offers the ability to connect your esp8266 directly onto the yellow female pin sockets and have a wireless preprogrammed relay working. Note: you need to purchase an ftdi programmer, flash the ESP with Arduino bootloader, write your Arduino code to toggle the relay when a wireless signal is received and then use this product to connect onto the esp8266 to wait for a signal to toggle the relay from your app or device. 

The added bonus is you can create your own encrypted automated home system that runs on your own protocol. The board will require an external 5v to power the board that can be tighten with the screw terminal blocks. You can use the relay to act as a switch and turn on or off devices that run at a max of 5amps 120VAC. (note the relay may state 10amps, but we think the copper trace and screw terminal can only provide up to 5A ~6A safely). 

It also includes a reset button, so if the program hangs you can reset the device.
