    Kygo,

    Thanks for bringing this to E2E, and great news that we have a win with the TLIN1029A-Q1!

    • RXD has the correctly valued pull-up to a logic voltage.
    • TXD and EN are connected to MCU, correct.
    • VSUP is correctly decoupled.
    • LIN bus looks correct except the pull-up VSUP is 30k instead of 1k. Is there a reason the pull-up resistor is valued this high?

    For the layout, can you share it as a .zip of a PDF instead? We aren't able to open 7zip files.

    Regards,

    Eric Hackett
