Hello, in order to print a PCB and weld a atsamr21g18a I need to buy an external antenna and a 16 MHz crystal. Any crystal with 16 MHz is ok? Or do I need a specific one?

In the page 1098 of the datasheet, it says that I should use a coil (L) - i thinks that's the name in english. What should be the value of this coil?

Thanks

This topic has a solution.

Also, look at the parts list of the Xplained-Pro board...
