    Create a custom board with MK20DX256VLH7 but not recognize via USB

    Hi guys,
    I developed my project using Teensy 3.2, and now I'm trying to produce a my custom board.

    I based myself on the schema that I found here

    I purchased the MKL02Z32VFG4 component with bootloader from pjrc.

    I produced a custom board, but when I try to connect via USB, PC doesn't recognize it.

    I have checked, many times, schema of my board but it'ss all correct.

    Is it possible that the schema needs other components that are not indicated?

    The schematic is proven and OK, many people used it. Can you post your schematic? Maybe something is missing.. And please post pictures of the layout and your soldered PCB!

    Breaking news!
    Thank you for support and problem was a weld on the MKL02Z32VFG4!

    My biggest doubt was that the scheme needed other supporting components, but so, fortunately, it is not!

    Thanks again for your reassurance.
