Right now, the Arduboy is using:
- An 8-bit microcontroller
- Flash memory
- Black & white display with low resolution
- 1- to 4-track PWM audio
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.
