### ⭐⭐⭐⭐⭐ Perfect
*by T***E on September 27, 2025*

### ⭐⭐⭐⭐⭐ It makes wiring SO much easier

I've used a lot of various models of Arduinos, and always find wiring them into the finished product to be a bit of a pain. With this on top of an Arduino Mega, all the pins are exposed with screw clamp terminals to make solid and lasting connections.

### ⭐⭐⭐⭐⭐ Love it
*by S***E on October 17, 2024*

This works super well. I was sick of putting jumper ends on wires to hook up the the arduino. Have not had any issues with the terminal screws which hold very tightly. I've accidentally stepped on a wire and it broke on the other end of the wire rather than pulling out of the terminal. There was no damage to the terminal. I really like the additional grounds that are provided.
