Adafruit GPIO Stacking Header for Pi A+/B+/Pi 2/Pi 3 [ADA2223]
Brand: Adafruit
Connect your own PCB to a Raspberry Pi B+ and stack on top with this normal-height female header with extra long pins.
The female header part is about 8.5mm tall, good for small HATs that do not to clear the USB/Ethernet jacks.
This header has extra long 10mm pins, compared with our plain version which is the same base height but has 3mm header pins instead.
With 10mm you can have a HAT that has extra pins to stack another HAT on top!
