MacroFab is now shipping the kits out! US backers can expect their kit to arrive within 3-5 days of shipment notification, and International backers will have their kits in 6-10 days. I have also finished the first version of the Arduino library, with three examples to make sure you have something to start playing with as soon as you unpack the kit. Check out the library at https://github.com/jarek319/EPD215 I'll be filling out the Wiki with frequently asked questions, so feel free to reach out to me with any questions you have after checking that section.
I'm working on a very beginner-friendly step by step tutorial, and I will post it to Adafruit's Learning System within in the week. I'll make another update to let you all know when it's ready!
