The WeMos D1 Mini family of boards is one of the latest additions to the ESP8266-based IoT ecosystem. The WeMos D1 Mini Relay Shield includes a high-power SPDT relay that allows you to control electrical devices that run on AC Voltage up to 250VAC or 30VDC.
The WeMos D1 Mini Relay Shield is designed so that pin D1 on the WeMos D1 Mini v2 board is connected to the control side of the relay. This means that setting pin D1 to a HIGH state will power the relay coil and activate the relay (connecting the Normally Open and Common pins). Conversely, setting pin D1 to a LOW state will deactivate the relay.
What makes the WeMos family of development boards for the ESP8266 great is the availability of stackable, plug-and-play shields such as this WeMos D1 Mini Relay Shield. Without much fuss, it’s very easy to connect, control, and monitor a wide variety of electronic components to the ESP8266. The WeMos family is a great solution for building projects quickly using the ESP8266 SoC.
Different users have different applications for the WeMos shields, thus we’ve found that the easiest way to please everyone is to ship the boards with the headers unsoldered. Each board in this kit includes a pair of Male, Female, Long Female pin headers for you to choose. Soldering is required for installing the header pins!
