user4189: I am looking at this: https://learn.adafruit.com/16-channel-pwm-servo-driver
Although it’s meant for servos, I was wondering if I could use them to control vibration motors.
Motors like these: Diameter Flat Button Type 3V-4.5V Cellphone Micro Vibration Motor (Pack of 3) https://www.amazon.in/dp/B07CQXZBZD/ref=cm_sw_r_cp_tai_yzSvDb8V7JAF4
Any suggestions? I would like to control about 200 motors with minimal number of controllers.
Each motor should be controllable individually.

user4143: Not directly, no.  Those boards are designed to generate a low power PWM signal for passing to a servo with a built-in controller. To use that output directly with a motor you will need to add a transistor to each output to control the motor.
