I want to buy a crystal or oscillator for the Arduino Uno. So what model should I buy?
As the attached picture shows, where is the crystal or oscillator?Who knows it? ;)

The UNO R3 uses ceramic resonator with in-built capacitors. See XTAL1, XTAL2 pins on the ATmega328P. It is single SMD part. It is not specially critical part and can be replaced with the crystal even with the better stability and accuracy but with external capacitors to the GND ~12-22pF each. The part has label CSTCE16M0V53-R0 in the schematics.

You can use a crystal resonator instead (both sites have them) and don't need the caps, but depending on your application, the resonator may not be precise enough.

The exact model of crystal or resonator is not critical, you realize. Most of us use a crystal when we use an atmega328p in a custom design, for example, while the official boards use a resonator.

@Ardino-Uno-Crystal I just cleaned out your 5 requests for Arduino crystal from a bunch of different threads.
Please don't do that again.
