I have these 2 motor shields: Adafruit Motor Shield V2 and Seed Motor Shield V2.

They are stacked on top of an Arduino UNO.

My question is, how can I power 2 of those motor shields with one 3S Lipo battery(Turnigy 3S 2200mAh 20C), given that I have 6 identical 4.6-6V DC gearmotors?



You can avoid using a linear voltage regulator. Try using this voltage regulator.

You will get 5 Volts 2 Amp output which should be easy to connect to motor shield's input power ports.

  • Thanks. How is this different from UBEC suggested by @Majenko ? – Abay Bektursun Sep 30 '16 at 20:07
  • No, you really don't want to run a motor on a regulator. Choose an appropriate power source, use a regulator for the electronics and use PWM to deliver an appropriate amount of power to the motors. – Chris Stratton Oct 30 '16 at 15:55
