I have an idea for a new module like module C but don’t know if it would be feasible to make.
Perhaps create a module with 4x ethernet ports like module C, but that all supply PoE natively on the ethernet ports, like a PoE ethernet switch.
Since power supply requirement would change, maybe add a barrel connector to the board so a different power supply could be connected to the ethernet module itself instead of MOX module A.
Instead of powering MOX by the 12V power supply or PoE going into MOX A maybe, if possible, power the entire MOX from the power supply going into the new MOX module that supplies PoE on its ethernet ports.
This would be an interesting addition and I think provide a lot more functionality for users of MOX if it were possible to make such a board or something similar.
Just thought I would share the idea
