1-CH 12V Relay Board Trainer Kits Start with low-altitude1 CH 12V Relay Board This is a small and easy to use 1 channel relay board that operates on 12V. Use it to control one 240V power appliance directly from Arduino, Raspberry Pi, and other microcontrollers or low voltage circuits. Perfect for switching 240V appliances lights, fans, etc, and even high power motors at lower voltages. The board uses a high quality relay, which can handle a maximum of 10A 250 V AC or 15A 125V AC. Each relay has all three
