## Overview

The Electronics-Salon Arduino Screw Terminal Block Breakout Module is a pre-assembled, high-quality interface designed for Arduino UNO R3. Featuring a 3.5mm pitch screw terminal block compatible with 26-16 AWG wires, a 40-pin IDC header for full Arduino pin access, power-on LED indicator, and a handy reset button, it streamlines prototyping and wiring tasks with professional-grade materials like copper contacts and a dual-layer FR-4 PCB. Note: Arduino UNO board not included.

## Description

Terminal Block Breakout Module - for Arduino UNO R3. the item has been soldered and assembled. Terminal block pitch 3.5mm/0.138", wire size range 26AWG to 16AWG, strip length 5mm, screw M2 steel, pin header and cage copper. Standard IDC40 pitch 0.1" header, you can use 40pin FRC(flat ribbon cable) connector cable connect all Arduino Uno pins to peripheral equipment. With power on LED indicating. red reset button on the side. with a ICSP adapter connect header. FR-4 fiber glass PCB, dual copper layers. NOTE: the item not include Arduino Uno module

Review: This really helps with wire connections. - When going from prototyping to a more permanent installation of an Arduino UNO R-3/4 this work so well. Very easy attachment to the Arduino that then allows connection of I/O wiring using screw terminals. Compact design. Great quality and great cost. Compliments the Arduino boards.
Review: Good but pricey - Easy to use, makes prototype work nice. Not for production work due to price, but for testing it's a must have.

When going from prototyping to a more permanent installation of an Arduino UNO R-3/4 this work so well. Very easy attachment to the Arduino that then allows connection of I/O wiring using screw terminals. Compact design. Great quality and great cost. Compliments the Arduino boards.

### ⭐⭐⭐⭐⭐ Good but pricey
*by T***N on May 31, 2026*

Easy to use, makes prototype work nice. Not for production work due to price, but for testing it's a must have.

### ⭐⭐⭐⭐⭐ Works great for securing wires to your Arduino Uno board
*by J***N on April 9, 2025*

Picked this unit up because I was tired of my dupont wires always popping out of my Arduino boards. The unit is well built and holds wires tightly. It's a bit expensive for such a small devise but it will get lots of use.
