M5Stack Grove digital relay controlled at 3.3 V DC, capable of switching loads up to 250 V AC / 3 A. Safe and easy high-voltage control via the standard Grove interface.
The M5Stack Grove Relay module is a digital normally open switch designed to control high-voltage and high-current loads, far exceeding the capabilities of standard Arduino boards. When the control signal is HIGH, an onboard LED illuminates and the relay contacts close, allowing current to flow through the load.
Safety warning: exercise extreme caution when switching mains voltages. If in doubt, consult a qualified electrician.
