## Description

This GPIO header adapter is designed specifically for the Raspberry Pi 400, converting its rear-mounted 40-pin GPIO header into two standard 40-pin headers for easy expansion. The colour-coded header makes it simple to identify pins at a glance. Since the Raspberry Pi 400's GPIO header faces outward from the rear of the keyboard, this adapter provides a convenient way to connect HATs, breadboards, and other accessories that expect a top-facing header. Key Features Dual 40-Pin Headers – Two standard 2×20 GPIO headers for flexible expansion Colour-Coded Pins – Easy identification of power, ground, and signal pins Designed for Pi 400 – Purpose-built for the Raspberry Pi 400's rear GPIO layout Ideal For Connecting HATs and pHATs to the Raspberry Pi 400 Breadboard prototyping with the Pi 400 Running multiple GPIO expansion boards simultaneously

**Product Type:** physical
