Just spotted Adafruit's new(ish) 2.42" 128X64 OLED... perfect for a super sized Arduboy!
and it will only double the cost to make em aaaaaand thats assuming the next one has no upgrades to anything else
Wrong driver IC unfortunately.
Shouldn't be too difficult to adapt the library to use this screen. It's using a variant of the SSD controller so it's very likely just a different initialization routine.
