Replace 16MHz Resonator with 16MHz Crystal


is it possible to take a 32U4 Microcontroller (Leonardo) from a board running on an 16MHz resonator and implant it on a board running on a 16MHz Crystal?


Yes, it will in fact make the millis MORE accurate as well.

Thanks for your reply. But will it run without any hassle "pick and place"?

I have somewhere read that there are "Fuses" that have to be set??? :cold_sweat:

You need two capacitors that match the crystal. 22 pF will typically work, but for highest frequency accuracy, consult the crystal data sheet, taking both the specified load capacitance and the PCB stray capacitance into account.

The fuses need not be changed.

That sounds fantastic to me.

Thanks a lot!
