Involvement:General (knows how to use it) - Ownership:1 week to 1 month
This relay has an easy and understandable layout. It activates the relays on "high trigger", which I find useful for my applications.
This module has male headers. If you combine this module with an Arduino, female headers would've been more handy.
I wish I had bought the 8 Channel version instead of the 4 Channel. I'm using this one for 1 month, and I already have a destination for each of the 4 relays. I like this module, really works as designed.
This is value for money. If you want relay functionality for your Arduino, then this is the relay-module you need.
