Good news at last! They are on their way.
UPS claims they’ll be delivered to Mouser on Monday, and hopefully they’ll quickly make their way to you after that. While you wait, be sure to double-check your delivery address so they all arrive to the right place. If you have any shipping or order questions you can contact Crowd Supply support.
And you may also want to take a look at a couple things I’ve been working on: The Epi 32U4 data sheet and KiCad footprints. They’re still work in progress, so don’t expect flawlessness yet. Or ever for that matter, I’m new at this.
