Review: Reliable relay module, works as expected - I purchased this SunFounder 2-channel 5V relay module for a small electronics project, and it works exactly as advertised. The board is well built, clearly labeled, and easy to integrate with a microcontroller (Arduino/ESP-based setup). The optocoupler isolation is a nice safety feature and gives extra confidence when switching external loads. Both relays trigger cleanly at 5V, and I’ve had no issues with false switching or noise. Screw terminals are solid and make wiring straightforward. Overall, this is a reliable and beginner-friendly relay module that’s great for automation, DIY projects, or learning electronics. Good quality for the price — I would definitely buy it again.

### ⭐⭐⭐⭐⭐ Great relay

The relay works very well with Arduino. Simple wiring and the relay is operating properly.

### ⭐⭐⭐⭐⭐ Great Product - Well built and rugged - Does the Job!
*by M***S on March 18, 2017*

SunFounder 5V Relay Shield Module for Arduino UNO 2560 1280 ARM PIC AVR STM32 (4Channel) I am extremely happy with this board. It works flawlessly with the Arduino. It is responsive and VERY easy to use. Remember though, that its logic is Active Low, so when power is first applied from the Arduino, the low state of the pins causes the relay to turn on until the Arduino has time to set them to active high, thereby turning them off. I solved this problem using a 2N2222 transistor and a 1k Ohm resistor between an Arduino pin and the 5 volt input to the relay. Now, when the Arduino powers on, there is NO power to the relay board UNTIL the program tells it to do so. GREAT PRODUCT - HIGHLY RECOMMENDED!
