## Description

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 Adafruit's [plain version](https://core-electronics.com.au/gpio-header-for-raspberry-pi-b-2x20-female-header.html) 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!

You'll get one header per order.

**Note: The Raspberry Pi Model A+, Raspberry Pi 2 and Raspberry Pi 3, Raspberry Pi 4 are also compatible with this product!**
