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
- Keyed Connectors – Polarised for correct orientation
- 0.1" Pitch – Standard spacing compatible with breadboards and breakout boards
- 6-Inch Length – Compact cable for clean setups
Compatibility
- Raspberry Pi 3 Model B / B+
- Raspberry Pi 2 Model B
- Raspberry Pi Model B+
- Any board with a 40-pin GPIO header
Package Contents
- 1× 40-Pin GPIO Ribbon Cable (6 inches)

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine 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 serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
