Need to stack a board on the Raspberry Pi? This header is compatible with all 40 pin GPIO headers found on the Raspberry Pi A+, Pi B+, Pi 2, Pi 3B, Pi 3A+, Pi 3B+, Pi 4, Pi 5 and all versions of the Raspberry Pi Zero. The header creates a between board height of 11mm on the Pi and has extra tall pins allowing for additional boards to be stacked on top. Our Raspberry Pi 1/2″ Hat Hardware kit is a close fit with this header and creates a rigid platform for your next Pi based electronic project!
