We're modeling the Spark Maker Kit after the SparkFun Inventor's Kit:
So you should expect roughly this set of components included - with a Spark Core instead of an Arduino.
2013! Sorry about any confusion. That is definitely a typo, we'll be delivering the 'One of Everything' in September 2013. We can't edit it in the campaign. Oops :)
Sorry, but unfortunately no; the Core is intended to be used as a client in a standard Wi-Fi 802.11b/g network.
The Spark App will be available for iOS and Android.
The Core is 0.8" (2cm) wide and 1.3" (3.3cm) tall. We will publish a mechanical drawing shortly so you can start thinking about building projects with the Core!
ONE OF EVERYTHING: 1 Core
CONNECTION KIT: 5 Cores
BEST FRIENDS KIT: 5 Cores
VITAL CONNECTION: 10 Cores
