For making a standalone arduino in pcb

Projects
1

I tried to build a stand alone arduino and for that I need a 16mhz oscillator but I am not getting in the library how could I get

I would probably draft my own. The schematic symbol is just a rectangle labeled “Clock Osc” or (something similar) and a reference designator beginning with “A” or “U” (or maybe “X” or “Y”). The footprint is often similar to an 8-pin DIP IC, but with only 3 or 4 pins.

smallest package in that frequency range with reasonable accuracy I could find myself some time ago for running an AVR @ 12MHz (selection criteria: safe operating conditions at 3.3V, but YMMV)

Anyhow, as you can see from the spec sheet they’re available in 16MHz as well. Thus what you asked for:

symbol (footprint pre-assigned):
crystal_12mhz-15ppm_4p-3.2x2.lib (759 Bytes)
footprint:
Crystal_3.2x2.5_4P.kicad_mod (2.0 KB)

I have done a few Arduino like designs and always use a 16MHz crystal, a couple of 22pF capacitors and a 10M resistor
