OONO 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.

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 .

A little pricey, bur good quality

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.

This kit is great! Fits right on my Arduino and makes wiring up the pins a LOT easier, especially when I have wires than don’t always want to stay right in the pin holes. The screws are great and makes the entire process overall faster, as I am not looking for wires that fell out. It is a small setup and looks pretty slick. I wish I had started using one years ago.
