Hi.
Yes. I think so… But I recommend to check with a multimeter first.

Thank you for the nice tutorial.
Regarding separate power supplies…. I do have a nice one that can supply 5.1V, 2.5A that I use for most of my Pi projects.

If that power supply is directly plugged into my Pico H’s micro-USB port, can I safely get up to 2 A for my (small metal) servo from the Pico VBUS pin 40?

Thank you, DS

In reply to Dee Kee.

Hi.
Yes. Ideally, you should use a separate power supply for the motors.

You can drive the control signal of the DF05SR from a Raspberry Pi Pico 2W directly, but you should NOT power the servo from the Pico’s 5 V pin / onboard regulator.

A Raspberry Pico (or Pico 2W) cannot supply enough current from its 5 V pin or regulator to power a servo—especially under movement or stall conditions. This can reset the Pico or damage its regulator.

Hi,
Great tutorial, but one line could be improved in first example. Middle value is not half of max value but must be added also half of min value.

half_duty = int((max_duty+min_duty)/2)
