This 2×20 (40-pin) IDC box header is the matching connector for 40-pin GPIO ribbon cables used with Raspberry Pi models that have a 40-pin GPIO header. Solder it onto perfboard to create a breakout point for your Pi's GPIO, or use it in any custom PCB design.
Key Features
- 40-Pin (2×20) – Matches the Raspberry Pi 40-pin GPIO layout
- Keyed IDC Box Header – Ensures correct ribbon cable orientation
- Through-Hole Mount – Solder to perfboard or custom PCBs
- 2.54 mm Pitch – Standard 0.1″ pin spacing
Compatibility
- Raspberry Pi 5, 4, 3, 2, B+, A+
- Raspberry Pi Zero / Zero W / Zero 2 W
- Any 40-pin GPIO ribbon cable
Ideal For
- Custom GPIO breakout boards
- Connecting a Pi to perfboard via ribbon cable
- PCB designs requiring a keyed GPIO connector
Package Contents
- 1× 2×20 pin IDC box header
Warning: This header is for 40-pin Raspberry Pi models only. It is not compatible with the original Raspberry Pi Model A/B which uses a 26-pin GPIO header.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
