Stackable 0.100″ Female Header: 2x20-pin, Straight
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.
We also carry an extra-tall 2×20 stackable female header that includes an extra 0.3″ spacer, which gives it the necessary height to clear all of the components on the Raspberry Pi Model B+ or the Raspberry Pi 2 Model B. (And if you just want a standard, non-stackable 2×20 female header, we have that, too.)
