Just to mention that while the plugin crystal allows for a different one to be swapped in, contact can be sometimes erratic, causing the program to halt. Wiggling the crystal a little gets the program to restart. Fortunately I'm only using the dev board to prototype a circuit and will later have a PCB with a soldered-in crystal for a project.
