Review on Tolako Arduino Indicator Channel Official by Doug Bunkers

Ordered and delivered in 2 days via Prime. The packaging and everything else was excellent and it arrived in good condition. I just hooked it up to my circuit and tested it. I applied 5 volts to the positive and negative pins of the terminal, and when I apply 5 volts to input 1 (somewhat oddly labeled IPP ON (perhaps the input port is on?) I hear the coil inside the switch with a nice click I have a separate circuit that runs on 2.3V with a 330 ohm resistor and a small red LED This circuit goes through the NO side (normally open) so it doesn't light up until I 5 Apply V to the IPP when I do this I hear a click and I can see the red LED light up It's just a test build but this is one of my first projects and it's so cool I apply/switch off the 5V and on very quickly hear nice click turn on the relay and see the red led turn on and off very quickly enjoy and a great little product I will be buying more from this company because the product works well and the shipping was great .
