GikfunScrew Shield Expansion Board for Arduino UNO R3 EK7007

Worked right out the packaging. Because it’s not sent on a hard package you may have bent pins. This is the reason the cost is cheaper. Most items like these are sent as light weight as possible.Make sure you have a set of very small screw drivers to fit the terminals. Once the screws are open you may have to insert the screw driver into the hole to help open it up. Works just fine for 22awg and smaller wire. I tinned my wire before inserting

The pins are thin and somewhat fragile. The screw heads are very small. I had to use a jeweler's screwdriver. I had hoped this would make it much easier to wire up 8 LEDs but the task is still pretty difficult.

These clip nicely to the arduino UNO3, and even with a shield on top, if there are female connectors, these wil fit as well. If you want to fasten longer wires to your board, perhaps to use sensors several feet away, these screw terminals work really well. You can also use them like a removable harness: Leave the wiring intact, and just remove this screw terminal. Overall, its a nice upgrade to your arduino.

It makes installation of my Arduino UNO a snap, just put the wires into the terminals, screw them in place to clamp them in, and you're done. This also makes swap-outs a breeze...just unplug the boards and out pops the UNO.

I bought this parts for my son's school project with the Arduino board. Shipping was fast! The item worked great once I got it installed. Installation was a bit difficult because many of the pins were bent pretty good (perhaps during shipping) and the back headers on top were a bit bent which caused them to not align properly with the shield that I had originally mounted on the Arduino board. With little effort and good care I was able to straighten the pins and headers and got all my parts to fit as expected. All in all the price was good, shipping was fast and I got the working parts needed for our project.

Overall this worked for my purposes - I needed access to pins after inserting a TFT LCD onto the Arduino Uno.The pins were inserted into a foam block upon arrival, but they were still bent a little when I removed them. Because they're so flimsy it was easy to bend them back to the proper orientation.My biggest complaint is that solder was visible quite far down the pins, and one even had it going all the way to the end in a few places. I think the quality of solder detracts from what could be a better product. Having said that, the board does sit proud of the UNOs headers when fully inserted so it really didn't matter as much. Even with the solder it inserted and worked fine.For the price, I'd probably buy one again if I needed it.

This Screw shield provided easy- access to Arduino UNO I/O pins without soldering. However, it does extend the size of the UNO which created some close fitting when I mounted my UNO on a DIN rail. For most users, this will not be a concern. Highly recommended. Would purchase again.

Me hace el trabajo mas fácil.
