Expands the Raspberry Pi 400's GPIO pins with a colour-coded header for easy expansion
This adapter is designed specifically for the Raspberry Pi 400 barebone mini PC. It provides a color-coded GPIO header expansion that simplifies connecting external components. The layout helps builders identify pins quickly during prototyping or hardware experiments. It suits hobbyists, educators and developers who need accessible GPIO access on this platform.
The adapter extends the Raspberry Pi 400's GPIO pins into a color-coded header for easy expansion. It comfortably handles typical prototyping tasks such as connecting sensors, LEDs or small HATs. The design offers no additional buffering or level shifting, so it runs out when projects require electrical isolation, voltage translation or higher current drive than the Pi's native pins can supply. Builders needing those features must add external circuitry.

The adapter is designed for the Raspberry Pi 400, so it aligns with that board's 40-pin header and can be added without modifying your existing unit.
Each pin group on the adapter uses a distinct colour; when the block sits flush on the Pi 400 header the coloured rows line up visibly, confirming full contact.
