WeMos D1 10A 5v Relay Shield V2

This WeMos D1 10A 5v Relay Shield V2 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. 

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. 

Included with the shield is a set of header pins that can be optionally fitted (soldering required) to allow the shield to be easily inserted and removed from the D1 mini.

Features

• Onboard transistor relay driver.
• Onboard freewheeling diode for protection from relay coil inductive kick.
• Includes screw terminals for securely wiring electrical devices to the relay’s high-voltage side
• Breaks out all the WeMos pins for easy access when stacked on top of the WeMos D1 Mini V2
