DIYables Screw Terminal Block Expansion Board for Raspberry Pi
Click to zoom






Quick Overview
The DIYables Screw Terminal Block Expansion Board provides professional wire connections for Raspberry Pi models including Pi 5, 3B+, 3B, 3A+, 2B, 1B+, Zero, Zero W, and Zero 2 W (does NOT fit Raspberry Pi 4B). This pre-assembled board breaks out all 40 GPIO pins to clearly labeled screw terminals with 3.5mm pitch, eliminating soldering and enabling secure, vibration-resistant wire connections perfect for permanent installations, industrial applications, and projects requiring reliable connections.
Simply plug the board onto your Raspberry Pi's 40-pin GPIO header and connect wires directly to the screw terminals—no soldering, no breadboards, no fragile jumper wires needed. The industrial-grade screw terminals accept both solid and stranded wires for professional, maintainable connections in robotics, home automation, industrial control, and educational projects.
