Powering the Micro Maestro

Robotics and electronics discussion Electronics
1

Hello,

First of all, I’m a novice when it comes to electronics. My aim is to motorize an aircraft gauge with two servos (https://www.pololu.com/product/1248) using the Micro Maestro USB controller (https://www.pololu.com/product/1350).

My question is regarding power. I understand that I can power the controller processor off USB but need additional power for the servos. I would like to power these from the mains as the gauge will be stationary and always close to power sockets. What do I need to consider when powering servos from the mains? Any special hardware requirements? Any recommended products?

I would appreciate it if someone could help steer me in the right direction.

Thanks! :smiley:

Hello.

You can power the Maestro from a single power supply. The supply must be within 5–16 V, be within the servos’ respective operating ranges, and be capable of supplying all the current that the servos will draw. You can read more about using one power supply for your Maestros and servos in the “Powering the Maestro” section of the Maestro user’s guide.
