G40-2M2F 40-Pin GPIO Splitter & Extender for Raspberry Pi

This passive GPIO expansion adapter provides two 40-pin male GPIO headers and one 40-pin female GPIO header, allowing easier access to GPIO pins when a HAT is installed.

The raised design provides clearance above the Raspberry Pi 5 Active Cooler, helping keep exposed GPIO pins away from the metal heatsink. The included dual-male pin headers can also convert the female GPIO connector into a third male GPIO output.

Two removable GPIO pinout labels are included. Apply them after choosing the installation direction, making pin identification easier when the adapter is reversed or used with Raspberry Pi 400/500.

Two lengths of brass standoffs 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.
