Elecrow Raspberry Pi 400 GPIO Header Adapter
Elecrow Raspberry Pi 400 GPIO Header Adapter
The Elecrow GPIO Header Adapter for Raspberry Pi 400 provides a standard 40-pin female header that breaks out the internal GPIO pins from the keyboard-case. It allows you to connect HATs, bonnets, and breadboard projects directly to the Pi 400, restoring the versatility of a traditional Raspberry Pi’s exposed GPIO.

What You Can Build With This
- Attach a Sense HAT for environmental sensing and LED matrix projects.
- Connect a motor driver HAT to build a Raspberry Pi robot or rover.
- Plug in a prototyping HAT or use a ribbon cable to a breadboard for quick sensor experiments.
- Add a small TFT display and buttons for a portable retro-gaming console.
Compatibility
The adapter is designed exclusively for the Raspberry Pi 400 and its internal GPIO connector. It provides a 1:1 pin mapping of the 40-pin header with 5V, 3.3V, I2C, SPI, UART, and all standard GPIOs. Most Raspberry Pi HATs and common maker boards that follow the 2.54 mm pitch standard are supported, provided they fit physically in the case cutout.
Wiring Notes
Insert the flexible cable gently into the Pi 400’s GPIO slot with the metal contacts facing the correct direction (markings on the adapter board indicate orientation). The breakout board then offers the same pin layout as a classic Raspberry Pi. Do not exceed the Pi 400’s per‑pin current limit of 16 mA and total 3.3 V rail current of 50 mA.
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 other Raspberry Pi models?
No, this adapter works only with the Raspberry Pi 400. Standard Pi boards already have an exposed 40-pin header and do not need this breakout.
Can I use jumper wires directly with it?
Yes, the female header accepts standard male-to-male or male-to-female jumper wires. You can also plug the whole adapter into a solderless breadboard.
Does it include mounting hardware?
The package includes the adapter board and flex cable; screws, standoffs, or a case are not provided. You can mount the board using M2.5 standoffs if your project enclosure has appropriate holes.
📦 Free Setup Handoff Document Included
