These guys make the best screw sheilds. The design is awesome and I love the multiple voltage and ground terminals. It made wiring easier and less chance for mistakes. I've tried other screw sheilds out there to save money but I always end up ripping them out and putting these in.

I was looking for something like this; it makes the connection pins more robust and allows for more permanent designs without losing the flexibility. It is well made, a clear upgrade to board with the Uno form factor.

4.0 out of 5 stars Mostly a great module with just a couple of minor annoyances.
Reviewed in the United States on March 3, 2024

First off this module works great for permanently connecting wires to your Arduino Uno R3 or R4. The layout is easy to understand and labeled well. Having all the extra ground terminals is a God send. If you need to hold wires securely in an Arduino for a permanent install this works wonderfully.

Those minor annoyances?
First is something I'm sure the manufacturer can not improve on. Once you have a wire screwed down in a terminal it blocks the terminal behind it. You can bend the wire out of the way but it can be difficult especially if you are using heavy wire. If, like me, you resort to using breadboard jumpers for troubleshooting, the terminal in the next row becomes inaccessible. But I don't see any better way to arrange the terminals so I think the manufacturer has done the best possible.

Second, it seems a bit pricey for what it is. But for most people it's likely worth it.
