Using Arduino Due to power up 2 servo motors

Hi!

I was wondering if it is wise for me to use the 5V pin of an Arduino Due to power up 2 servo motors via a breadboard. The servo motors can be found using the following link: DSS-M15S 270° servo with analog feedback - DFRobot

I read that it is wise to use an external power supply to power up any servo motors and not the Arduino. However, all of the examples that I saw that stated this were using an Arduino Uno, which is weaker than an Arduino Due.

Due to this, I was wondering if that recommendation is for any Arduino or just the Uno?

Thanks!

I would always suggest an additional power supply for a servo.

I say No, and No. As a rule, never power motors from the Arduino 5 volt pin. The same goes for using breadboard in the powering chain for motors.

Yes it is.

How, in what respect?

The "UNO" is an Arduino. There are some 20 different Arduinos. UNO is one of them.

Thank you!

Thank you!

As for the comparison between the Due and the Uno, I was thinking in general. For example, the microcontroller of the Due is stronger, and there is more memory and SRAM.

How? Do You intend to use it as a crow bar? Joking.
Memory capacity, number of I/O pins, UArts... differs, yes. What do You have special needs for?

Define "stronger".
The output ports are "weaker" (can source/sink lower current).
Logic voltage is lower (3.3volt instead of 5volt).
It is faster, and has more memory, but you don't need that for servos.
For servos it could be "better" (and cheaper) to use an Uno or Nano.

And bear in mind that, even after you have the power and connections right, i.e. NOT via a breadboard, it's still the case that some servos will not work correctly with a 3.3V control signal. The RC PWM signal referred to in your servo specification is normally 5V.
