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...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...
