    Hello
    On the Arduino uno board there is 16 mhz crystal.
    Does anyone know if this 16 mhz crystal is it SERIES type crystal or is it 16 mhz crystal a 18 PF or 20PF crystal?
    Thank for the help mrel

    mrel,

    You need 2 ceramic 22pF load capacitors in parallel if you use an external crystal. This picture shows it nicely. If you use a ceramic resonator instead of a crystal, you don't need the load capacitors.

    The thread i post about the crystal,what i trying to find out is what kind of crystal on the arduino uno broad I know it a 16mhz crystal But is it a(series type) or (18pf type) or (20pf type).
    Because went to Digikeys website to buy crystal.
    Digikeys lists three different type crystals there are series,18pf,20pf.
    So question is what kind of crystal on the arduino uno broad (series ,18 pf,20pf ).
