Thank you for the reply. I am planning to use Sub-Micro Plastic Planetary Gear motors (136:1) with Raspberry Pi 3.
Due to space constraints, will it be OK to use A-Star 32U4 Micro for wheel encoders?
I initially thought of using DRV8835 Dual Motor Driver Carrier, with Raspberry Pi.
Can A-star also drive the motors through this motor driver?
If micro-controller drives both motors and encoders, is it possible to use Baby Orangutan which also has small size motor driver.
Thank you for your support.
