sorry for late reply, If you are using nodemcu you can reduce the circuit to a very large extent because it will shrink the size of the entire circuit and i would not suggest you to use arduino nano because it comes with limitations on power supply, either choose uno or as i recommend using nodemcu board, the circuit remains same where as you will add extra motors, any help you can ask in comments
Bro we are using Arduino Uno for our 6×6 bot project is there same process for that either we have to use Arduino nano
