## Overview

The OONO Ultra-Small GPIO Terminal Block Breakout Board Module is a pre-assembled, high-quality accessory designed specifically for Arduino Mega-2560. Featuring 2.54mm pitch terminal blocks, M1.6 steel screws, and a durable FR-4 fiberglass PCB with dual copper layers, it ensures secure, vibration-free connections. The package includes multiple breakout modules, nylon standoffs, nuts, and a screwdriver for easy and stable installation, making it an essential upgrade for professional-grade prototyping and development.

## Description

1, The item has been soldered and assembled. Support for Arduino Mega-2560. 2, Terminal block pitch 2.54mm/0.1", wire size range 28AWG to 18AWG, strip length 4.5mm, screw M1.6 steel, pin header and cage copper. 3, FR-4 fiber glass PCB, dual copper layers. 4, Pin header connect to Arduino board. The breakout board is firmly fixed to Arduino-Uno through standoffs and nut, and will not shake. 5, Packing list: 3x(1 set, A B C each one) terminal block breakout modules, 6x 11mm nylon standoffs. 6x 6mm nylon standoffs. 6x nylon nuts, 1x small slotted screwdriver (NOTE: the item not include Arduino Mega-2560 module).

Review: Since parts are small, a little difficult to screw in the supports but, very stable once installed. The terminals worked perfectly and the pins fit snugly without tightening too much. Well labeled. I recommend securing wires before connecting to the Mega board if you’re just transferring. I Highly Recommend.
