Raspberry Pi 400 GPIO Header Adapter, 40-Pin Breakout
Raspberry Pi 400 GPIO Header Adapter — 40-Pin Breakout
The Elecrow Raspberry Pi 400 GPIO Header Adapter is a simple board that plugs into the horizontal GPIO connector on the Raspberry Pi 400 and converts it to a standard vertical 40-pin header. It restores the traditional Raspberry Pi GPIO layout, letting you attach HATs, expansion boards, and other 3.3‑V peripherals without awkward cabling. Ideal for prototyping and permanent projects that need reliable pin access.

What You Can Build With This
- Attach a sensor HAT (e.g., Sense HAT, Enviro+) to your Pi 400 for environmental monitoring.
- Connect a motor driver HAT and build a small robot or camera slider.
- Use an LCD display HAT to create a compact info dashboard.
- Pair with a T-cobbler and breadboard for quick prototyping with LEDs, buttons, and sensors.
Compatibility
Designed exclusively for the Raspberry Pi 400, this adapter uses the standard 40-pin GPIO layout found on Raspberry Pi 3 and 4 boards. Most HATs and add-ons that work with those models will function correctly. The board operates at 3.3 V logic; do not connect 5 V peripherals directly to the GPIO pins without level shifting.
Wiring Notes
Simply press the adapter onto the Pi 400’s GPIO block—no soldering or extra wiring is required. The adapter is keyed by the Pi 400’s connector shape, but double-check that pin 1 aligns with the red stripe on the adapter. For external connections, use the male header on top, which mirrors the standard Raspberry Pi pinout.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with standard Raspberry Pi HATs?
Yes, the adapter faithfully maps the Pi 400’s GPIO pins to the standard Raspberry Pi 40-pin layout. Most HATs designed for Pi 3B+/4 will work without modification.
Does it require any soldering?
No soldering is needed. The adapter uses pre‑soldered female and male headers—just press it onto the Pi 400’s GPIO connector.
Can I use this with a breadboard?
The male header on top can accept a 40-pin ribbon cable connected to a T-cobbler, which then breaks out to a breadboard. Direct breadboard insertion is not possible due to the dual-row layout.
