Availability date:
Here is a ready to use Arduino Relay module for your microcontrollers-based projects.
This module provides all the necessary features for a quick implementation.
Practical, it will offer a galvanic isolation (the high-voltage circuit is never in contact with the control circuit) allowing the control of more powerful devices (such as a fan, a small water pump, a low power motor, etc).
It has a TTL-compatible input, which allows to connect it directly to a digital output of your Arduino.
It also includes an LED type indicator, to know if the relay module is active or not. The module also incorporates an anti fly-back diode (see our explanations for the mini relay kit).
The relay module has a 3-pin connector.
