1 channel Relay Shield V2 Version 2 for WEMOS D1 mini ESP8266 WiFi Module

This relay shield is designed to be used with the WeMos mini & mini Pro ESP8266 based development boards. Adding this shield to your WeMos mini development board provides it with the ability to switch high voltage, or high power devices from a single digital pin. Included with the shield is a set of header pins which can be optionally fitted (soldering required) to allow for the shield to be easily inserted and removed from the D1 mini. Although this module is intended for use with the Wemos development boards it can of course also be used as a standalone relay module requiring a single 5V supply and one digital pin (5V & 3.3V compatible) to control it.
