Hi,
I looked in the documentation on the sailoog website and it stated that there are 9 free GPIO pins.

but there's one problem how do i access the GPIO pins there is a header on top of the hat, according to the documentation those are GPIO pins (IO) but the pins are smaller then the raspberry GPIO pins and the pins are not markt with a number and you can't find documentation of the pins.

I just want to fit a simple switch to turn off my raspberry pi, but i can't find access to the GPIO pins.
