This Wemos D1 Mini Shield allows you to control up to 4 separate channels via MOSFET relays (fast and durable) with 6-30V and 2A per each channel. Depending on the input power (6-30V), the outputs are powered via the relays with the same voltage. E.g. you can control solenoid valves or pumps with 12VDC or 24VDC depending on your needs.

The shield is addressable via an I2C controller with 8 different addresses which can be selected via an onboard switch. Therefore, it can be stacked and used with multiple other shields.

Please use the provided ESPHome YAML file to easily flash your Wemos D1 Mini. Once connected to your WiFi network, the Wemos D1 Mini is automatically detected in HomeAssistant . The code can be found on Github.

Please select whether you would like to receive the board with the header pins and screw terminals soldered or not soldered. Not soldered is recommended if you plan to stack boards. If you order the board soldered with the header pins and screw terminals from the pictures it is ready-to-use and does not require any soldering on your side.

Wemos D1 Mini is not included unless selected via the options menu!

This board is compatible to the Misitemita project for easy integration into waterproof junction boxes.
