Stackable 0.100" Female Header with Extra 0.3" Spacer: 2x20-pin, Straight
We have 25 units in our Sydney Warehouse available for immediate dispatch.
Overview
This stackable 40-pin female header features two rows of 20 pins spaced with a standard 0.1″ (2.54 mm) pitch; this spacing is the same as on most solderless breadboards and matches 0.1″ male header strips. The extended pins allow multiple units to be stacked as popularized on Arduino shields, enabling removable daughter boards that can access pins without blocking them. The 2×20 size is notably used on the Raspberry Pi Model A+ and Model B+ as well as the Raspberry Pi 2 Model B, Raspberry Pi 3 Model B, and Raspberry Pi 3 Model B+, and its height matches our 18.6 mm M2.5 standoffs for Raspberry Pi.

This header includes three 0.1″-thick spacers, which gives it the necessary height to clear everything all the components on the Raspberry Pi Model B+ or the Raspberry Pi 2 Model B. The locations of these spacers can be adjusted if so desired to provide more clearance, or they can be removed to provide less clearance:
The spacers can be adjusted on the Stackable 0.100″ Female Header with Extra 0.3″ Spacer: 2×20-pin, Straight. |
