ESP8266 Relay Shield for Wemos D1 Mini
This single-channel relay shield connects directly to a Wemos D1 Mini development board, giving the ESP8266 microcontroller a hardware switch for mains-level loads. It is intended for hobbyists and engineers adding remote or automated control of lights, heaters or other appliances to an existing ESP8266 project.
One-channel relay output decides fit
The board provides exactly one independently switched relay contact, so it suits projects that need to toggle a single circuit. Builds requiring two or more separately controlled outputs will need additional shields or a multi-channel module instead.

Which header layout does the shield use to connect with the Wemos D1 Mini?
The shield plugs straight onto the standard Wemos D1 Mini pin headers, matching the ESP8266 development board footprint.
