HCDC Screw Terminal Block Breakout Shield Module for Arduino UNO R3

Like it very much made my work more simple

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)

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.

This breakout board fits perfectly on the Uno model. The bolt holes line up allowing for a secure bolted connection to the arduino, but the pin headers are of a high enough quality that there is little to no concern of them coming apart accidentally anyways. The terminal screws are easy to access, turn easily, and provide a solid grip on the wires. The labeling on the terminal blocks is second to none, and makes prototyping, testing, and manufacturing of an arduino system an absolute breeze in comparison to breadboards, soldering, or plain pin headers. Easily one of the best accessories you can get for your Uno.

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
