This relay exceeded my expectations & is worthy of a review. The quality is very good, it has no feedback during switchiing & maintains a very stable slope on the current side, it literally outperfromed another unit I paid 10 times the amount for. I reccomend these (and the dual version) for anyone building arduino projects that need switching of an independant power source.

Relay does what it should, but the logic seems to be inverted. I also had some problem interconnecting this relay to a 3.3V digital output.

These relay boards work great. Because they have traces exposed on the backside of the board, I'd recommend putting a layer of tape on the backside of the boards to prevent shorts and prevent getting shocked.

really good product for home use
Verified purchase: Yes | Condition: New
Only worked with 3.3V for me despite being advertised as 5V. Seems like they tried to remove as many components from this relay board while keeping it barely usable.
