Hello, I am doing a robotic project. I have an old robot wth 12 servos. it was using and Arduino nano with a 16-channel PWM & Servo driver. Now I would like to substitude the Arduino with a Pi3 or Pi zero, as the Pi has a limited hardware PWM, Would it be better to use this 16-channel PWM & Servo driver?
Also later on, I would like to add some sensors such as proximity sensor to the bot, would it be better to leave the nano to handle the servos tasks and dedicate the pi to do the sensors tasks?
