    Hi all,
    Attached is my hardware tab screenshot on a Matek F405-CTR with blheli_32 ESCs. Does anything look incorrect?
    I kinda want to make GPS occupy UART 3 instead to free up UART 4’s potential use as an ADC, but I remember reading somewhere that UART 3 interferes with I2C bus which is required for compass. Is this true?
    And nice meeting you all! I’m a bit late to the party… Hope David the best of luck with what he’s up with next!

    No issues with using UART3 for GPS in this configuration.

    Thank you for your knowledge, unfortunately my impatient ass has already soldered GPS to UART 4, and by passing the test it gained the “if it ain’t broke don’t fix it” status.
    Nevertheless, I’ll have more peace of mind knowing I have a fallback even if I can’t get RSSI out on Ch16 to work.
