Snap a mini relay module to your M5Stack project

The RELAY unit implements a galvanic isolation to safely control a bigger load from a small signal.

The relay can be seen and used as an electrically operated switch. It used an electromagnet to mechanically operate the physical switch.

This module use a digital signal output from the microcontroler to control up to 30V DC (or 220V AC).
The relay output have 3 output:

  • COM: the common pin to the both contact descrived here below
  • NO: is a Normaly Open contact (circuit is open when the relay is not activated AND closed when the relay is activated)
  • NC: is the Normaly Closed contact (circuit is close when the relay is not activated AND open when the relay is activated).
