1-to-3 40-Pin GPIO Splitter Extender for Raspberry Pi

This passive GPIO expansion adapter converts one 40-pin female GPIO connection into three 40-pin male GPIO headers, providing easier GPIO access when using HATs, displays and other expansion boards.

The side-facing GPIO header allows compatible boards such as Raspberry Pi Sense HAT or display boards to be mounted vertically for easier viewing and access.

The raised design provides clearance above the Raspberry Pi 5 Active Cooler and helps keep exposed GPIO pins away from the metal heatsink.

It also works with Raspberry Pi 400 and Pi 500, bringing the rear GPIO connection into a more convenient working position.

Two standoff heights are included for different HAT mounting arrangements.

NOTE: This is a passive parallel GPIO splitter. All GPIO headers share the same 40 GPIO lines. The PCB marks the two pin rows as A and B for orientation reference only. Match A with A and B with B when checking corresponding headers to help avoid swapping the two GPIO pin rows.
