I’m wondering if a proffieboard could run the automation I think the main issue might be the 12v required to power the remote control tires and the other motors and automation.
The answer is yes, but with caveats.
It depends on how many things you need it to do, and what devices you need to control.
The proffieboard FETs can control a 12V thing through the FETs. (The actual max voltage possible depends on which FETs were actually installed, it can be anything from 16 to 60 volts.)
It’s also likely that a fair amount of work would have to be put in to create a prop class that does what you want.
