HATs and other add-ons • OpenCM 9.04 or Poppy Pixl Board - to control XL320 Motors

Hello everyone,

I want to control 5x Dynamixel XL-320 motors for a project i started (it have to be these motors, due to the design and properties etc.).
The basis should be an RPi3B, RPi3B+ or RPi4, depending on the possibilities.

Here are the two options that I have found as driver boards:
- Poppy Pixl Board: can control up to 6 pcs. XL-320. These are simply connected "in series". Control via GPIO pins. As far as I could see it, this board can be controlled with max. one RPi3, max. RPI3+.
- OpenCM 9.04: can control up to 4 pcs. XL-320. One port for each motor on the board. Can only be controlled via USB? Would also work with RPi4.

=> does anyone have experience with the boards?

The OpenCM would actually be ruled out, as too few motors can be controlled. Does anyone know whether 2 boards can be controlled with one Pi?
As far as I can see, the Poppy Pixl board is actually only for a specific robot kit. I'm a little worried that the programming would be too limited.
I would like to implement the program and the control generally via Python.

If anyone has experience with both or one of the two boards and could share their knowledge, I would be very grateful.
Many thanks for your help in advance!
