I found this crystal resonator XTAL-08900 in sparkfun-freq_control library. But I can’t find it in the website.
Is it a retired product ?
Should I use it or not ?
Where else can I get the product ?
Most of the parts in their library, they do not sell. Try search for it on Digikey or Mouser.
That would be this part: https://www.sparkfun.com/products/9420
Ah, so they do.
