Arduino Motor Shield (L298N) (SKU:DRI0009) Power Supply

Hello,

As I am about to try to use the referenced shield, I was wondering how to know if I need to use the external power supply for it or if the Arduino one is enough?

I am using an Arduino UNO and the motors (x2) are those ones: SKU: FIT0016.

Thank you for your help,
2016-03-25 22:17:22 hi Rivoire Pierre,

The power required is depended on the DC motor driver chip actually but not the motor ;) , and one more useful referrence could be found in its specification, Motor Driven Voltage:6.5~12v(VIN Power Supply), 4.8~35V (External Power Source)

I just was posting something related, you may have a look Power Supply for Arduino card (Motor driver+ servo ...)

To power it externally, Does the power required depends on the motors? If I have 2 6V motors, should I put a 6V Power supply or is there some adapting done by the shield?

Thanks again

You will need to use an external power supply such as a 7.2v lipo battery, or an AA battery pack. The arduino can only control the logic of the motors and wont provide enough amps to power two motors.

hope this helps!

Thanks a lot!

For the theory part: how can I know what I can use without external power? What data shall I look for?
I understand that the answer is "not much"...
It seems that if I want to use motors and/or servo, I need the extra supply except exception.
