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, and Raspberry Pi Zero. The header creates a between board height of 7/16″ on the Pi and has extra tall pins allowing for additional boards to be stacked on top. Two of our 1/2″ nylon standoffs are a close fit with this header and create a rigid platform for your next Pi based electronic project!
