Relay board module is used for controlling higher current loads from your microcontroller development board, pc parallel port or arduino uno. This board has one (1) on-board relay which can switch up to 7amps. Relays terminals (c, nc, no) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor bc547 hence your input device, such as arduino, is protected from relay circuit. There is free wheeling diode which will further protect your microcontroller from relay kick back. This is a 12v 1-channel relay interface board which can be controlled directly by a wide range of microcontrollers such as arduino, avr, pic, arm, 8051 and so on.

Awesome product to buy for beginners
I am using this product since last 4 months. It works correctly. It has 2 Leds on board. Best product for beginners because you only need to connect 3 ports Vcc,GND and INP.

Nice ones
Nice ones . I am using this to trigger the 12 DC fans in the bathroom exhaust on motion sensing. Using from last 3 months and works continuously without problems.

Incorrect picture is shown!!!
The relay works good but it does not look like the picture shown. I bought 4 of them and all were not similar.

Great Relay for DIY experiments with Raspberry Pi.
Works great as a relay with my Raspberry Pi. Programmed to control it with the RPi. Was surprised by the tiny size much smaller than the picture.

Seller does not test the product before sending
Both the time seller sent broken/not working relay. Also they are selling it very costly. You can easily buy this for 60-75/- @ robokit.co.in OR robu.in
