## Description

Product description Ultra-Small GPIO Terminal Block Breakout Board Module for Arduino Mega-2560 Product Description： The item has been soldered and assembled. Support for Arduino Mega-2560. 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. FR-4 fiber glass PCB, dual copper layers. Pin header connect to Arduino board. The breakout board is firmly fixed to Arduino-Uno through standoffs and nut, and will not shake. 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: Great product! - Much easier to use when prototyping. All connection screws are accessible without removing an entire row of connections. This was designed by someone who has suffered that pain! Good job!
Review: Perfect Fit - 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.

### ⭐⭐⭐⭐⭐ Perfect Fit

### ⭐⭐⭐⭐⭐ Best terminal block for Arduino Mega!!
*by M***T on March 16, 2026*

The best thing ever! Originally used a different connector which sits on top but unable to remove an individual wire. This lets me have access to each wire individually.
