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

Excelente producto y más para la interconexión de Arduino con dispositivos y de esta manera los cables no se mueven

Toutefois, le tournevis joint est de mauvaise qualité, aprés quelques vis serrées il est tordu et inutilisable

Very good breakout board for Arduino. Makes hobby projects easy.

A little pricey, bur good quality

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.
