First robotics project

Hi, I have some motors with Omni wheels out of an RC toy that only require about 2V to run at a good speed for a robot. As the toy, the motors get a little over 3V & it FLY’s across the floor! The motor controller’s that I have only operate lowest at either 3V or 4.5. Adafruit Cricket & Feather Wing

The ask; could I use a buck converter for each motor (signal from the motor controller → 5V PWM → buck converter → 2V PWM → motor) (& the same for each of 4 motors) to bring down the PWM signal from 5V to the needed 2V without messing up the PWM signal?

Yes, that is likely going to be the simplest way to reduce the voltage down to 2v

Best of luck!
