There had been talks to add some SD card for storage or a 32-bit microcontroller for faster processing or a color display. But the problem with these upgrades is that you lose the simplicity, lightness and resource-bending playfulness of the Arduboy platform. And at this point, you might as well upgrade to a… Pi Zero for example!
Which is why I introduce you my new Hackaday Prize project (click on Like to vote for it ):
For the pros and cons of using a CPU versus a microcontroller, I let you start the discussion below.
pi zero’s are cool, when you can get your hands on them for $5, otherwise $10 shipping kills it for me. with that said, i have two somewhere laying in a box. two $15 pi zeros just siting in a box along side my pi1 and pi 2
