“Firstly, it arrived very quickly, even out here to Luxembourg. I comes with no instructions but that doesn't matter as the manufacturers website www.cytron.io has very clear diagrams and data. I wanted it to control small water pumps. 2 minutes connecting it and it was up and running, in test mode as it has test buttons built in. A bonus which I didn't realise when I ordered is that each one is 2 channel and even more, it can control a stepper motor! For €3 you can't go wrong”
