Power through peripheral SOM

How it works

  • Ethernet will allow us to send data and power the cameras at the same time

  • Information travels from camera(s) to a network switch, which connects to raspberry pi, which connects to display

  • Network switch is essentially a mux that can choose which camera’s stream information to send

  • Add power breakouts to peripheral board to supply power to cameras

  • Send information through CAN?

Pros and cons

Tip

Simplicity

Tip

Keeps peripheral SOM simple

Tip

Possibly easier for wire harnessing

Warning

Long ethernet wires

Warning

New wiring requirements needed

Warning

Need to purchase/make(?) network switch

Tip

Possibly not that much more to be added to peripheral SOM

Warning

Running video information over CAN is probably a bad idea

Warning

Board may not be able to supply enough power
