Stackable 0.100 ″ Female Header with Extra 0.3 ″ Spacer: 2 × 20-Pin, Straight

Description

This extra-tall stackable 40-pin female header features two rows of 20 pins spaced with a 0.1 ″ (2.54 mm) pitch. It includes three 0.1 ″ -thick spacers for additional clearance, and the extended pins allow multiple units to be stacked as popularized on Arduino shields. The 2 × 20 size is notably used on the Raspberry Pi Models A + and B +, and the extra 0.3 ″ of height allows for stacked boards to clear all of the components on the Raspberry Pi B +.

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 ″ bad 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 Bs, 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.

We also carry a shorter 2 × 20 stackable female header (with no spacers) and a standard (non-stackable) 2 × 20 female header.
