Overview
The Adafruit 1979 is a specialized 40-pin board-to-board female header designed specifically for Raspberry Pi HATs and expansion boards. It features extra-tall pins that provide 23mm of clearance above the PCB, allowing for the stacking of multiple boards or the placement of bulky components like heatsinks and capacitors between layers. This header uses a standard 2.5mm (0.1 inch) pitch in a dual-row configuration to match the Raspberry Pi GPIO pinout.
Why Choose This Part
The 23mm height is ideal for clearing the USB and Ethernet jacks on a Raspberry Pi, which standard headers often struggle with. Its 40-pin layout is gold-plated for reliable contact and matches the exact physical footprint of the Pi B+, Pi 2, Pi 3, Pi 4, and Pi 5 models.
Applications
Raspberry Pi HAT Prototyping
Connecting custom daughterboards to a Raspberry Pi while maintaining clearance for tall components on the base board.
Multi-Board Stacking
Creating vertical stacks of Raspberry Pi-compatible hardware where standard headers do not provide enough physical separation.
Heatsink Accommodation
Providing enough vertical space to mount active cooling solutions or large passive heatsinks on the Pi CPU without interfering with the HAT.
