Took me ten minutes to wire this into my Arduino project, and the NC ports make it dead simple to switch between off and on states without any cross-talk. The 5V input works straight off the board's regulator, so no extra power headache. Two relays in this little package is exactly what I needed for
Swapped out the bulky setup in my garage door controller for this little 5V module and the NC ports made wiring the fail-safe a breeze. It's been running 24/7 for two weeks without a single hiccup, and the optoisolation keeps my Arduino safe from any power spikes. Honestly, for the price of a coffee
These little boards are perfect for my Arduino projects, the 5V logic level means I don't need any extra components to switch my 12V loads. Both relay channels clicked on cleanly when I tested them, so I'm grabbing a few more for the next build.
