    Hi. This thread is old but I will try to join here with a request. I have a board that works something but not quite. After visually inspecting it I discovered missing components in two places on the board from the top. Bottom left corner next to the USB ports a row of components next to JL1 and bottom right corner opposite, one component next to PD101. Perhaps someone would be so kind as to advise what I should solder in. Thank you in advance for your kindness Close-up of a circuit board with missing components near markings JL1 and PD101.

    Here you have everything.
    There are no components next to YL1.

    Thank you. Now I know what is missing. Now just the values.
    PR101 1K resistor
    Still need:
    CL29
    CL21
    CL20
    Below two places RL11 and RL4 but I think they were empty?

    CL20 = 1uF 6.3V 0402
    CL21 = 0.1uF 16V 0402
    CL29 = 15pF 50V 0402

    RL11 and RL4 and RL9 empty by default, this is space for optional 4.7k 5% resistors 0402.
