    It won't :) (probably)
    Different style of touchscreen .
    HDMI rather than I/O pin driven.

    I'd suspect that with the correct drivers loaded it will work, but I don't have the time at the present to try and hook one up and see.
    I have a few laying around that we keep attached as default Pi touchscreens and they are great for that. I don't have any of them connected to the Pi in the C2 :)

    The R2 uses a larger screen, but AFAIK it is still using the Pi I/O bus for the touchscreen side of things

    Yes the default R2 screen uses GPIO for touch input. There is a thread that explains what needs to be changed to use a USB based touchscreen in the Capacitive Screen upgrade mod.

    Please note that any software changes will need to be reapplied if Robo ever upgrades RoboOS (or any part of their software).

    Fantastic! Looks easy enough.

    Also, by any chance do you know where to make an edit to expose the cursor? It would make so many of these LCD issues easier if the mouse cursor was still visible.

    It should be in /boot/cmdline.txt, the first and only line should have a reference to cursor
