Ganglion P2&P3 Pins

I'm relatively new to the forum and am having trouble finding the layout of the P2 and P3 pins on the board. Would anyone know what the role of the P2 and P3 pins are or know if there is a datasheet for the board?

    Are you referring to the channel input pins on the Ganglion? These are labeled with plus and minus and the channel number. So you might be assuming P is the same as plus (+) ? Either is fine.

    OK, I think you are actually referring to the 'Plug' number designations on the board. These are header pin plug connectors to external boards. In the case of Ganglion, the P2 and P3 header plug connectors are for connection to the "Wifi Shield" board. Which is currently deprecated, but may eventually be revised and returned to production.

    Yes, that was what I was referring to. Thanks once again for your help. Have a great day.
