    Kygo,

    This schematic looks good to me:

    • All logic signals (TXD, RXD, STB) are routed to the MCU.
    • VCC is properly decoupled.
    • CANH and CANL pins have choke, filter capacitors, and TVS diodes. One thing I noticed is the placement of the filter capacitors, I tend to see them after the common-mode choke (other side closer to the rest of the CAN bus) rather than between the choke and the pin. This way isn't wrong, I just wanted to point that out.
      • I also noticed no termination on the bus pins. Can you explain why?

    Regards,

    Eric Hackett
