Well, I sold out over the holidays more quickly than I expected so I didn't have more on order. They are on order now. The raw boards are expected to ship (from China) on the 20th so they'll probably be here around the 25th. Most of the parts are coming from the US so that should only be a couple days. One part is coming from Hong Kong though... ordered it on Jan 3rd and it still hasn't even left.
So... I really don't have a good answer for you. My best guess I'm saying is the end of January or beginning of February, but delays are the norm, not the exception, in electronics projects.
I suggest ordering one
as the backorder list is starting to build. That way when they do arrive you'll be among the first to get them.
