Incompatible HATs (partially)

[GeekyTim]

So far I have found the following HATs which use GPIO 23 which is not brought out on the PiSquare. You may want to mention them in the documentation.

Some are unsuitable for the PiSquare (e.g. audio boards) and some will just be missing a button/function.

@GeekyTim brought out how? are you saying pin 12 on the 40pin as shown to mapped to GPIO 23 in the diagram is in fact not plumbed in the production sample you've received?

@GeekyTim Actually some technical reasons we will not mention GPIO23 in PiSquare, we working on it, and in the future, we will update this.

[GeekyTim]

Excellent! Good to know.

The diagram shows that the equivalent gpio23 pin on the RPi is not labelled on the Pi Square.

I see what you mean now - I was talking about GPIO pin 23 from the Pi - that one is not labelled as connected on the PiSquare.
