Which PYBD pins are GPIO?

[kbrenner]

I cannot find this information at https://pybd.io/hw/pybd_sfxw.html#pins-and-gpio, so I was wondering if someone knew which pins were GPIO on the Pyboard D-series? I am designing a shield for my PYBD-SF6W and need to ensure that I do not route a path to a pin that is not GPIO. Thanks!

Just to clarify -- if you're using the pins on the edges, the it's just the regular pyboard X1-12 and Y1-12 which are all GPIO.

If you're using the WBUS mezzanine connectors, then no. Probably best look at the schematic -- https://micropython.org/resources/PYBD_ ... matics.pdf

In particular note which ones are either reserved or have a secondary purpose (e.g. SD or USB or USR).

The WBUS_DIP68 diagram identifies further pins which are available on the mezzanine connectors.
