If I didn't want to power the motors via the batter pack what parts would I need to power from a wall plug?
Hello, Joe.

If you want to power your Maestro from a wall outlet, all you need is an appropriate wall power adapter:

From there, I recommend using our DC Barrel Jack to 2-Pin Terminal Block Adapter to connect the power to your Maestro:

Thank you Patrick, I also got additional info from a question in the forum:
https://forum.pololu.com/t/how-to-power-12-channel-servo-with-one-supply/18108/3
Is there any info on how I can add buttons or dials to control the servos similar to the video shown above?

Thanks,
Edson
Hello, Edson.

You can see how to connect buttons or switches in the "Attaching Servos and Peripherals" section of the Maestro user's guide. Additionally, you can find multiple example scripts for using inputs with servos in the "Example Scripts" section of the same user's guide.

Hi,
I am totally new to the world of robotics, servos, motors etc. What I am trying to achieve is basically having a computer case with a lid that can be opened from a windows application and it should be powered/controlled through a USB header. As the case is tiny (only 3L volume), I am looking for very small components and most motors, servos or linear actuators are way too big. I found your brushless DC motors like the 298:1 Micro Metal Gearmotor LP 6V https://www.pololu.com/product/1094
Is it possible to control this motor with the Micro Maestro?

thanks in advance,
Wolfgang
Hello.

Please note that our Micro Metal Gearmotors are brushed DC motors (not brushless). The Maestro cannot directly control a brushed DC motors like that. If you want to control a brushed DC motor through a USB interface, you could use something like our G2 Jrk Motor Controllers, but please note that you would have to add extra components like a potentiometer to do closed-loop position control like a servo. Alternatively, you could use a G2 Simple Motor Controller (SMC) which supports limit switches that you can use to stop the motor at the extremes of your range of motion.

The combination of a Micro Maestro servo controller and a micro servo is probably the more practical option, and it is fairly comparable in size to a Jrk or SMC paired with a Micro Metal Gearmotor, especially if you have to use additional components like a potentiometer or limit switches to get it to behave like you want.

If you want to continue the discussion or need more assistance in choosing components, please post a request for help on our forum, which is a much better place for this kind of discussion, and we would be glad to assist you further.
