Use this 16MHz Resonator instead of a regular crystal in your next project.
Since they have the capacitors built into it, they are easier to connect and behave the same.
Connect the two outer pins to the crystal-in/out of your circuit, and the inner pin to ground.
Easy to use with any microcontroller or device that requires an external crystal.
If you want to build your own standalone Arduino this is the easiest way to do it.
