Ultra-Small GPIO Terminal Block Breakout Board Module for Arduino UNO R3

I really like these terminal blocks. They give you a nice easy way to attach wires to your Arduino GPIO pins. I only needed one of them for my project, and the other one wouldn't fit on my relay board, but it's no fault of the terminal block, it's the relay board blocks off where the last 2 pins should go with its own relay connection block. I could cut off the pins if I really wanted to install one on top of a relay board on that side, but I don't need any connections there, so I decided to save it for another project. I also haven't installed the stand offs and screws yet, because the pins on the relay board are too short and I needed to put extensions in to prevent the relay board from shorting out on the Ethernet connector, so now I need some custom standoffs to make it work. Again, it's not any issue with this product, it's the relay board with the issues. It does work well enough on my workbech without the standoffs.

perfect for working with arduinos

A little pricey, bur good quality

Aunque la devolví , está bien practica pero para el montaje que tengo tenía que extender algunos cables y decidí dejar todo como lo tengo , pero si en un futuro decido cambiarlo todo , la compraré .

Esta hermosisimo!!!

I got this when I started using Arduino boards, but I have not found it particularly valuable in my projects. However, I accept that my needs may not match the needs of others, and I wouldn't want to dissuade others from using this.It is a well designed accessory that does exactly what it is supposed to do. It is simple to use and the price point is reasonable. I didn't drop it a star, but given the price of other similar products, it may be just a bit high for what you get. I would recommend doing a little research to make sure you are getting the best breakout board for your needs.

Totally my fault, I didn't pay enough attention to the description and went by the photos assuming the plastic standoffs and screwdriver were normal size. The standoffs shown in the ad are like half size and that screwdriver is less than 2 inches long. The screw terminals are extremely small, too small for my intended use, I doubt that you could get anything larger than a jumper wire inserted and even then I would not have any confidence that the wire would be held securely. The photo shows a normal 3mm standoff, a standard size small screwdriver, and a competitor's screw shield which has pretty small screw terminals itself. I give it 3 stars because it seems fairly well made and it might work fine for somebody else.

This unit adds a terminal breakout board for accessing Arduino pins. Using a breakout board provides a secure way to attach wires to the Arduino when the project is subject to vibration and heavy use. The terminals accommodate up to 18 AWG wires.Things I like: Easy to assemble. The standoffs and nuts are tiny and easy to lose, but two extra nuts, two extra long standoffs, and two extra short standoffs are included in case you lose one. As a minor bonus, the standoff posts that screw into the bottom provide nice little 6 mm feet for the Arduino. The posts rigidly attach the breakout module to the Arduino so they can't wiggle apart. The pins are clearly marked and easy to read.Things I don't like: nothing really - it's a well-designed quality part.Other things: The terminal screws are very tiny, measuring about 1.5 mm across. A tiny flat blade screwdriver is included, but you can probably use a screwdriver from an eyeglass kit. If you're interested in an alternative solution, search Amazon for "DIN rail mount breakout module for Arduino." These are much bigger and of course more expensive.Bottom line: except for being a little pricey, I like this module. I won't need it for most of my projects, which are just fine using jumper wires and a breadboard. But this will be perfect for when I'm trying to build something more permanent and robust.
