ElectroCookie Uno Terminal Block Shield Kit, Compatible for Arduino Uno R3, Push-in Simple Spring Connector Expansion PCB Module

Works great for Uno rev3

Fits the Arduino perfectly and makes prototyping much cleaner.

I'd give it a 4.5 if that were an option. It would be a 5 except for two things, first, one of the standoff holes ( the one closest to the USB ) was slightly out of position and I was unable to use that hole with a standard 3mm standoff, the other three worked fine. The board ships with some smaller standoffs that might work fine for all four holes but I needed to use the larger standoffs. Second, you can't insert a regular jumper wire with a square sheath, it won't fit, or at least none of the ones I use fit. The workaround is to remove the sheath from the jumper and apply a small piece of heat shrink to that end of the wire to prevent possible shorts. ( Or clip the end off of the jumper, strip it back and tin the wires, which is a lot more work.) Other than those two things I really like this board, the spring action holds the wires firmly in place and overall it's a well-made part.

It seems crazy to pay as much or more for this terminal block as for an arduino uno but I think it's worth it! Comes in a sturdy box resting on foam, so no bent pins. Extra ground and power (5v and 3v) locations to help power all the sensors etc. At first I was hesitant to push as hard as I needed to to insert the wires, but using the supplied little screwdriver I got used to it. So nice to move a wire from one location to another to fix my errors!

Good quality, nice colors

This HAT works great. Was able to use ferrules to connect to the header pins, and they held well, w/o issue. The electrical quality and functionality works well with no issues. The spacers were really not that useful as they are the wrong size, but using different spacers, and secured the HAT, and have not looked back.

There was some sort of glue or something jamming up several of the spring contacts, had to scrape it away with a razonr blade. Then it was still so hard to push the springs down for several connectors that it was just really hard to use. Issues also with the standoffs not quite fitting right. Overall, the fit and finish on this product just don't justify its price. I made it work, but I don't want to use the thing again and I won't be using this product in the future. My advice is stick to screw terminals.

No matter what I do I cannot make it work, pushing the tab, I see the contact inside moving but pushing the wire in does not work. Tried with few different wires (the male connectors (same as the ones that go into Arduino directly, also tried the wires that came with the terminal block shield). Asked question here, asked the support, no solution. Likely will have to return it.

Great way to wire a uno R3 very easy to understand and use

arduino project

Muy practico para realizar pruebas y fiable para montaje final

Dieser Terminalblock ist eine praktische Sache für diverse Arduino Projekte, passt hervorragend in einen Schaltkasten und alle Kabel werden per Klemmkontakt aufgelegt. Kann ich weiter empfehlen.

The Elelctro Cookie Uno terminal Block Shield is what I was looking for quite a while. I would normally use a male to male header wire and connect the other end to a bread board. I also found a small terminal block with the same spacing as the arduino and pressed it into the arduinos female header. This product is an Arudino shield that uses its male headers which are lined up exactly like the Arduino Uno pins. The shield has 4 rows of push and insert terminals that grabs the wire and holds them tightly. The rows represent all the Uno I/O, plus Analog terminals. and everything else the UNO has to offer.Each row has a 3.3V, 5V and a Gnd Terminal. No need top put all those ground wires in a big bunch. Lots of terminal spaces for them. The push and insert terminals hold the wires tight enough so you won't have any loose connections. The terminals all well labelled, but I need a magnifier to read them due to my aging eyesight. I would reccommend the terminal block shield to anyone looking for a way to wire up their Uno projects. It sure cleans up the wiring in those projects.
