Screw Terminal Block Breakout Shield Module for Arduino UNO R3

I've used several of these on various Arduino Uno driven devices, and I consider them to be an integral part of building a functional device - as opposed to a test-bed use of a Uno. These provide secure, stable wiring options. They are not perfect. Wiring routing requires planning, and installation is affected by the lay of the wires, so plan carefully...don't just start hooking wires anywhere. But if you apply reasonable engineering design effort into your work, these will vastly improve your final product reliability, ease of service and operational security. Five stars, no issues. Work perfectly for my uno-controlled Slowepoke Pickup Winder. (see photo)

Makes life easy for us non soldering people. Worth the money.

I’m not a fan of using pins so this allows me to quickly get my projects up and running without any hassle. Plus it provides more ground connections than available with the pins.

To change wires at will when testing your circuit this is great. Before soldering my circuit I always test to avoid problems afterwards. This makes it so easy to change wires. The screws are so tiny that I already lost two and I know I'll never find them back. But besides my clumsiness (and who tests all the wires of an arduino mega at once?) this is a real handy tool for prototyping

Terminal quality is excellent, no signal loss, freaking amazing product

Order these several times for projects at home and work and have been very satisfied with them. One thing that doesn't seem consistent is the reset button on the board. Some have come mounted on the underside, and other batches on the top. While it doesn't matter electrically, it can affect the enclosure that may have been designed for it one way or the other. Not a huge deal, but something to keep in mind.

While a bit expensive compared to the actual cost of my Arduino Minima, it saved a lot of work and made the connections to my circuit board much more secure. I have three circuit boards attached to my Arduino. Also have multiple Ground pins was helpful since I needed to ground all the circuit boards together as well as some additional 5V power supplies.

It looks a very good solution to take your Arduino board scale up for a project level But at the moment I mounted the device into it it caused the Arduino board to fail without option to recover I have tried it twice and it failed twice very disappointed

Like it very much made my work more simple
