The 4-Channel Relay Board makes it easy to control multiple high-voltage or high-current devices from a microcontroller, providing a simple and isolated switching solution for home automation, robotics, and other electronics projects.
Did you ever want to turn on and off a device that needs large current or voltage? Whether operating on DC or AC, a relay is what you need.
A relay is actually an electronic switch that is activated by a signal we send from a Dasduino or Arduino. This module further simplifies the whole process because it contains everything you need for the relay to work, and you just have to connect it to the microcontroller and power supply. You don't have to think about voltages and currents, insulation between high and low voltage or grounding, everything is already taken care of on the board. This product has 4 relays.
