This 40-pin (2×20) flat ribbon cable connects to the GPIO header on the Raspberry Pi, providing easy access to all GPIO, I2C, SPI, UART, and power pins. The 6-inch (15 cm) length keeps things tidy while giving you room to work with breadboards, breakout boards, and HATs.
The cable uses standard 0.1" pitch IDC connectors and is keyed for correct polarity, preventing accidental reversed connections.
Key Features
- 40-Pin (2×20) IDC – Fits the full Raspberry Pi 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.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
