I’m using this for some simple Arduino projects so nothing really taxing on it. It works great.
This relay module works just as well as some of the name-brand options I’ve used. It’s reliable, responsive, and the ability to trigger via either high or low level inputs is a nice touch, especially if you want to build in a simple failsafe or just avoid logic headaches.The status LEDs are a welcome feature too. They make troubleshooting way easier when your circuit decides to play dead. It’s not flashy, but it’s a perfectly good relay for DIY projects, automation setups, or robotics.Pros:Supports both high and low level triggering; great for flexible circuit design.Status LEDs help with quick diagnostics.Works reliably with Arduino, Raspberry Pi, and PLCs.Comparable performance to more well-known brands.Cons:Nothing special in terms of design or features.Doesn’t come with documentation, but it’s straightforward enough.tldr:If you need a basic relay that works and doesn’t cost a fortune, this one’s a solid pick. It’s not going to impress your electronics professor, but it’ll get the job done.
This little Relay controller board. Allows you to trigger heavier amperage attachments like motors lights with a simple 5 V trigger.. There are many uses for this. You just have to be creative. The board has great separations between high voltage and low voltage and it is isolated using a Optocoupler.
There's not a whole lot to say about this. It's inexpensive and works perfectly. Keep in mind that it's 24v!
