M5 Stack Mini 3A Relay Unit

RELAY as it says is an M5Unit that implements Relay functions. Relay can be used as an electrically operated switch, uses an electromagnet to mechanically operate a switch, where it is necessary to control a large power load circuit by a separate low-power signal such as digital signal output from a microprocessor.

The Relay support input voltage of up to 30V DC and 220V AC.

There are 3 pins named: ON, OFF, COM. You can program to make COM connect to ON or OFF, just by high and low output of a digital GPIO.

Applications:

Remote control of high-power appliances, such as refrigerators, air conditioners, TVs, etc.

Also checkthe M5 Stack Grove-T Connector, which comes in a package of 5 pieces. It is a T-shaped hub called CONNEXT-T, used for CONNEXT port expansion.

Also checkM5 Stack 1 to 3 HUB Unit. The HUB Unit is a device that allows you to connect more GROVE ports to your M5Stack device. This is useful if you want to use multiple sensors or other devices at the same time.
