Hi, I'm Orpheus Leap! Here to help you review your PR.

You can view a render of your board over on tracespace.io!

Happy OnBoarding!

I probably should mention some things about the circuit for the pcb, because it does not use a Voltage supply or Ground.

I color coded the tracks in the schematic so that half of them are yellow, while the rest are green (CAN bus colors). The yellow tracks are for high signals passing through the circuit and green tracks are for low signals.

When the switch is flipped one way, the yellow tracks should connect together, and when flipped the yellow tracks should pass through a 120 ohms resistor and into a green track. (terminating CAN)

On the PCB design, all the yellow tracks are on one side of the board while green tracks are on the other.

If you're going to verify the footprints I use, here are the links for the parts I am using. I forgot to link them in the design.
