With a 63 mR you only get span to 2.2V when you can go to 3.3 V on the input. You can use a 91mR instead to get more span to 3.18V and use more of the measurement range.

Label the frequency of your oscillator

Don't use global labels, use net labels instead here.

I think your still making changes so I'm gonna wait go more thouroughly through the schematic, but something I noticed is that your connector is backwards. You wanna connect the wires to the round part (red arrow)

Might also be nice to list the sensors the board is being designed around in the analog sensor sheet.

Also your missing a voltage connection for this LED

K, like was me and ash were talking about, this board isn't actually running any sensor on 3V3 and every other component can run on 5V supplied from the can bus. So you can get rid of the LDO (SPX 3819) and shift everything to 5V. That'll mean you have resize the current sense resistors, as well as the current limiting resistors on the LEDs, as well as replace other connections

voltage symbols should in general point up
Might be nice to list the sensors the board was designed for somewhere on the schematic
