How to attach a servo motor to VOXL 2

[ashwin]

Hello,

I am currently working on a project involving the VOXL 2 platform and would like to control a servo motor within my existing system architecture. Below is a summary of the current configuration:

• RC, GPS, and Magnetometer are connected to the J19 port.
• An FPV ESC is connected to the J18 port.
• The M0151 expansion board is connected to a Doodle Labs module.

I am considering two possible approaches for integrating servo motor control:

• Using the IO Expansion Board via a free UART Port on the M0151 Board
  I plan to connect the IO Expansion Board to an available UART port on the M0151. I would like to confirm whether this setup would support reliable servo motor control.

• Connecting the IO Expansion Board to J19 and connecting receiver to J2 terminal of IO Expansion Board

Could you please advise on the feasibility and potential limitations of both configurations? I would appreciate any insights or recommendations you may have.

Please feel free to reach out if any further clarification is needed.

Regards,
Ashwin

@ashwin Are you looking to control the servo via PX4 or with some custom software? What will the servo be doing?

@ashwin

Do you need to be able to control the servo from PX4 or it would be acceptable to have an API you could use on the CPU / Linux on VOXL2 ?

Hello @Alex-Kushleyev @Eric-Katzfey

I am looking to control the servo via PX4.
Essentially, it will be a command either from the RC or GCS to open / close the servo motor.

But, if that is infeasible, I can make it work via an API on the CPU / Linux on VOXL 2 to be controlled via SSH.
