GPIO Stacking Header for Pi A+/B+/Pi 2/Pi 3 [Extra-long 2x20 Pins]

As per the description - works as expected. Used it to put other I2C sensors on top of a Sense-hat board. So for accessing the GPIO pins in conjunction with a hat this is perfect.

Useful for accessing GPIO pins through PoE Hat

The Raspberry Pi PoE Hat is great, but it obscures the GPIO pins on a Raspberry Pi 3+ Model B. If I need both GPIOs and PoE, I use a Pololu 2x2 header (PL-1022) along with an Adafruit Extra Long Stacking Header (AF-2223). The Hat can be skewered (it's a tight fit) over the long headers of the AF-2223, long enough to poke through and reveal a male pin for me to access the GPIOs. But the extra height would disconnect the Hat from Pi's 2x2 PoE header, so I put the PL-1022 over this header to keep the Hat connected. For stability I recommend 15 or 16 mm standoffs in place of the 11 mm ones that come with the PoE Hat.
