Arduino Bluetooth micro-controller

Hi
I am fairly new to this Arduino platform.
As I uderstood Arduino UNO Rev3 is kind of a base to which several shields can be stacked and one of which is this bluetooth shield (see the link below)
http://www.amazon.com/gp/product/B007BYI172/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A30ZYR2W3VAJ0A
I couldnt locate this shield in arduino website

  1. However, Arduino website talks about this:
    http://arduino.cc/en/Main/ArduinoBoardBT?from=Main.ArduinoBoardBluetooth#.UyxOkPldWnJ
    As far as I can comprehend, this is a micro controller in itself like UNO R3, but I cant locate this in amazon for instance for making a purchase!
    Now. I am not sure, if this is a shield or a base by itself like Uno R3.
    I am seeking to know if I can buy this Arduino Bluetooth (BT) alone and if it works that way or I have to buy a UNO R3 along with a BT shield? In either case, please send me a link for an online store, which ships to Sweden.
    Thanks in advance.

Regards,
Subrat

Right.

Arduino is an open platform, not everything is made by the original Arduino people.

That's an Arduino Uno with built-in bluetooth. I don't think it's available any more.

You can buy a shield, or just get a bluetooth module: arduino bluetooth module for sale | eBay
