This is a very misleading Kickstarter. They open with a graphic containing logos for 10+ different wireless protocols (including WiFi!), but the board itself only supports a fraction of those. It has pads for two RFM12B module, a Z-Wave module, and an EnOcean module as well as a socket for an XBee module. They also included a few nice extras such as a real time clock and a temperature sensor.

However, you have to scroll to the bottom to see that the remaining "supported protocols" such as UMTS, 3G, 4G, LTE, WiFi, Bluetooth, Bluetooth Low Energy, X10, etc. are supported "via USB" or over the ethernet port. In other words, they have nothing to do with this project. You buy those adapters (separately) and plug them into any Raspberry Pi.

This looks like a decent PCB and case if you want to add an RFM12B, Z-Wave, EnOcean, or XBee module to your R-Pi and get a decent case, but they've stretched the marketing copy to include "support" for all of these unrelated protocols and features.

EDIT: As pointed out by unwind, this PCB has an include XBee header to support the addition of a Bluetooth, WiFi, or Zigbee module. If you're after these protocols CISECO (the company behind this kickstarter) has a £3.90 adapter board to connect these to the Pi: http://shop.ciseco.co.uk/slice-of-pi-add-on-for-raspberry-pi...
