Expansion ports
These tables shows the available expansion ports, their pin assignments and available functions. We have tried to only list those functions which makes sense, omitting details on functions where not all needed signals are exposed in the pin headers.
Note: Each Pxnn pin is also GPIO capable even if not explicitly mentioned in the tables.

Two 2x24 2.0mm male headers.
