I am redesigning my control box as after learning a bit more discovered a few issues I was previously unaware.
I have the standard £5 5 axis breakout board and using the UC400eth as well, my question is I power the BoB via USB 5v input, can I then connect the UC400eth to the PC5v and PC GND connectors on the BoB to power it also as at the moment I have a dedicated 5v PSU.

I currently have 48v PSU for the stepper drivers, 24v PSU for the pump, fans and spindle controls on the BoB, 5v PSU for the UC400eth

I am aiming to separate the VFD as was originally in the control box and also the pump.
