The old version used some components that were not compatible with 3.3v logic/voltage, such as the L293D to control the motors.
A new design is needed that can be used with 3.3v, and potentially also usable with 5v with minor changes.
Things I can think of that should be done as part of this task:
[x] Design new version with Fritzing
Confirm the new design is probably ok by testing various things with temporary code
