I am just beginner, so perhaps this question is not correct. I am going to build a robot car, and I am going to power it by using powerbank. My question is : is it enough for robot at all? I mean, is it enough to connect by usb only raspberry pi, and others as motor drive will get power from raspberry (+ raspberry vamera module v2)? If it is enough what is the maximum limit of it`s power? It is my first project, so i am worrying to burn it. Thank You too much in advanve!

I meant powerbanks like this: https://www.amazon.co.jp/s?k=power+bank&__mk_ja_JP=%E3%82%AB%E3%82%BF%E3%82%AB%E3%83%8A&ref=nb_sb_noss

  • Yes, you should power the motors using external power, from a 3V to 6V battery/power bank. The following posts might help.

  • Thank you for prompt reply and helpful links! I read that 9V battery could burn raspberry, and to be honest i am going to use powerbank to protect it. – Dias-77 Jul 24 at 1:17
  • Yes, even 5V power connected to a Rpi GPIO pin would fry the Rpi. The "Build a buddy" tutorial mentioned in my links are good for newbies to get started. Using L298N driver and 3V to 4.5V battery pack is good. – tlfong01 Jul 24 at 1:23
  • Yes, that was great tutorial! Thank you so much! There were used 4 batteries is it enough? Because the sensors and other details in my project a little more. I am sorry for asking again – Dias-77 Jul 24 at 1:42
  • 1.5V x 4 = 6V is only for driving cheapy yellow toy motors. That project.rpi.org tutorial actually suggests to use Lipo power banks, which are powerful enough for bigger projects. They also refer to GPIO.ZERO which has built in advanced motor control functions, and also stepping motors control. Sensors usually don't use much power. But toy servo motors, solenoids, even small, are power hungry. In short, just try to start with a 4.5V/6V battery pack, L298N motor driver, 2 cheapy yellow toy motors. The principles you learn can almost directly used in serious/industrial grade projects. – tlfong01 Jul 24 at 2:08
