Dynamixel xl320 power

Hi all, I want to connect 22 dynamixel xl320 to a raspberry pi 5 and I am unsure as to which other hardware I need to get to accomplish this.

After initial research I think the u2d2 control and u2d2 powerhub might be necessary, as well as a powersupply. However, I haven’t found any other projects which used more than 4 or 5 servos per one powersupply and u2d2/control/power combination.

So now I am wondering if I need to connect several of these, but that seems also not to be necessarily the correct answer…?

Maybe someone here has more understanding about this and an idea for a solution? Thanks!
