KeeYees 5pcs 1 Channel 5V Relay Module Board Shield KY-019 LED Indicator for Arduino + 3pcs 20CM 10Pin Female Male Jumper Wires

Got 5 needed 2, all 5 worked as advertised. Using with Arduino Uno.

Used to remotely control propane stove, get the place warm before driving up in winter. Works great. So far it's been connected, with circuit open, for two months. When I test energizing the relay, it works fine and will stay energized for hours until the place is warm or I remotely turn it off.

Seem to work fine. Signal line current is a little high with a 5V signal. Adding a current limiting resistor in-line with the signal line doesn't seem to impact performance. I went with 680 Ohm, but it seemed to still work with 1K or more.

Worked as needed for my remote project.

I previously rated this product not working based upon incorrect pinout which is a whole lot of on the internet, so please check on the raspberry pi website if you are not sure. I hearby correct my rating, this relay rocks it does work indeed - I highly recommend this product.

Handy little relay board, the wires are a plus.

Exactly what I wanted

cables were cables, all 5 relays didn't switch states, even though the signal led was on
