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

Works great for Uno rev3

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!

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.

Good quality, nice colors

I like this item overall, but more than once I’ve had to try a few times to get the untined 20AWG wire to stay in well enough to pass the yank test. There’s just no touchy-visual feedback to be sure when the wire is in the right position. Otherwise this board is a great addition for the uno if you are doing some DIY projects. Also wish the terminals were labeled up top not just on the board. But that’s getting picky;)

That the devices are expensive but work fine.Also that there is no decent equivalent in the china market that are easy to find.

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.

The stand offs are too short and will bend your board.Throw them away along with the useless ribbon cable.It is useless.Not impressed!
