This versatile relay shield allows you to control larger devices up to 10A using your Wemos D1 Mini

  • Simply connect the shield into your D1 mini and connect the device you want to control into the terminal block
  • The relay is designed to operate up to 250VAC or 30VDC at 10A
  • Capable of controlling 1 device (Single Channel)
  • 1 onboard LED shows you the state of the relay
  • The relay is activated when the input pin is pulled low to ground. If the input pin is floating or at VCC, the relay will inactivate

Refer to Pinout tab for an explanation of the relavent pins on the module


Warning
Although the board is rated to go up to 250V AC, we never recommend hobbyists work with such high voltages unless they are familiar with the dangers associated with mains electricity and are appropriately qualified


Working with high voltage electricity can result in personal injury and / or property damage
