..... I was thinking of using 4 isolated 12v supplies. One for each driver. Fran was telling me about a different tricky way that simulates isolation using some small inductors and capacitors as the pseudo isolated power supplies, so I might try that instead, but I'm a brute force, totally inelegant sort of guy. haha. (it's true)
If I'm not wrong, there are isolated -/+ regulated power supplies modules similar to the ones that are being in use now.
Can you please list the added improvements to this upgraded PCB revision?.

Some suggestions for the "To do List" that would make a great motor controller.

-Would it be implemented any temperature sensor readings, also through its serial port?, like a controller's temperature cut back and an additional motor temperature input sensor, (both in one OP AMP chip circuit) .
-Current sensor reading on DC (battery side) input? End user optional decision and budget.
-Selection of throttle input by resistive and/or hall effect.
