Stack multiple plates, breakouts etc onto your Raspberry Pi Model B+ with this custom-made extra-tall and extra-long 2×20 female header. The female header part has extra spaces to make it 23mm tall: when placed on your Pi, a PCB will clear the Ethernet and USB jacks. The stacky pin part is also extra-long, 10mm, so that when a standard 1.5mm thickness PCB is installed, there will be 8.5mm remaining, plenty to plug into.
You’ll get one header per order.
Note: The Raspberry Pi Model A+ and Raspberry Pi 2 are also compatible with this product!
