Overview

The Adafruit 4079 is a specialized female socket header designed to reduce the vertical height of Raspberry Pi HATs and Bonnet boards. This through-hole component features a standard 2.54mm pitch in a 2x20 configuration, specifically engineered for ultra-slim hardware profiles.

Why Choose This Part

The 4079 offers a significant reduction in overall stack height compared to standard female headers while maintaining a robust 3A current rating. The UL 94V-0 polyester housing and phosphor bronze contacts ensure reliable electrical performance across a wide -40C to +105C operating temperature range.

Applications

Low-Profile HAT Design
Allows Raspberry Pi HATs to sit flush against the Raspberry Pi PCB by removing the typical gap created by standard height headers.
SBC Integration
Provides a compact interconnect for any single-board computer using a standard 40-pin GPIO layout where vertical space is constrained.
Compact Industrial Enclosures
Enables the use of standard GPIO-based expansion modules in thin, rack-mount, or handheld industrial housings.
Custom Shield Prototyping
Used on custom PCBs to create removable connections with a 3A current rating per pin for power-heavy peripherals.
