    Yes, it's a limitation of the driver you're using. Something like a SmartMatrix can display thousands of colors with a Teensy: https://github.com/pixelmatix/SmartMatrix

    There's a built-in tool labelled "Serial Monitor" that you can access from the tool bar at the bottom of the window, the icon looks kind of like an (American) electrical plug.

    Unfortunately that's not how NAND flash works, you can clear bits from a 1 to 0 but not the other way, so you can't erase a single page, you have to use the block erase command.
