SB Components GPIO Expansion Board for Raspberry Pi 400

The SB Components GPIO Expansion Board for Raspberry Pi 400 is a purpose-built accessory that provides access to the General Purpose Input/Output (GPIO) pins of the Raspberry Pi 400. Designed to overcome the integrated nature of the Pi 400, it enables connection of Hardware Attached on Top (HAT) accessories and other GPIO-based components.

Overview

The board features dual 2x20 pin headers, allowing up to two HATs to be connected simultaneously. This makes it suitable for users who wish to use existing Raspberry Pi HAT accessories with the Pi 400. A supplied flat ribbon cable connects the board to the computer's internal GPIO pins.

Key Features

• Dual 2x20 pin headers for connecting two HAT accessories simultaneously
• Supplied flat ribbon cable for connection to the Raspberry Pi 400 GPIO pins
• Onboard LED indicators providing visual feedback on GPIO status
• Fully labelled pin arrangements to simplify identification during wiring and prototyping
• Compact board dimensions of 190 mm width and 80 mm depth

Applications

The board is intended for educators, hobbyists, and developers who want to combine the all-in-one Raspberry Pi 400 with the wider ecosystem of GPIO add-ons. The LED indicators assist with project debugging and operation, while the labelled pins help reduce errors during wiring and prototyping.

Choose the SB Components GPIO Expansion Board for Raspberry Pi 400 when you need expanded GPIO access for connecting HAT accessories to your Raspberry Pi 400 in a compact, clearly labelled format.
