Unit Relay
Description
RELAY as it says is an M5Unit that implement a 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 out put of a digital GPIO.
Features
- Single-BUS control
- Up to 3A @ 30 V DC or 220 V AC
- Software Development Platform: Arduino, UIFlow (Blockly, Python)
- Two Lego-compatible holes
Include
- 1x RELAY Unit
- 1x Grove Cable
- 1x 3.96 socket
Applications
- Remote control of high-power appliances, such as refrigerators, air conditioners, TVs, etc.

EasyLoader
EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification.
The relay coil is turned on and off, and the contact is used as a switch for circuit control.
