Wyze car firmware & motor control output signal

I would like to use the cam v2 firmware needed for the Wyze Car and controller app. The goal is to develop a low cost stem project for local school/boys and girls club. We would use low cost rc car parts since the wyze car is expensive andno longer available. Any info on the motor control output signal from the cam would be appreciated.
I apologize if this has been asked before and I failed to find it.
