I was studying the datasheet of Shield X-NUCLEO-PLM01A1.
This Shield is intended to implement Power Line Communication on DC voltage lines.
Why use two lines of cable pair for communication between the boards ???
It was not to use only the 12Volts power cable to communicate the data between the boards ???
Can someone clarify me ??
Did I misunderstand the proposal of this shield?
Thank you in advance for your support.
