Use RFduino to Run Arduino Compatible Sketches and Communicate With Your IPhone Using Bluetooth 4.0 Low Energy.

Wireless coin-sized Arduino compatible open-source micro-computer that talks to your iPhone using Bluetooth 4.0 Low Energy

The RFduino is a stand-alone board, just like the Arduino UNO. In addition, the RFduino has a powerful ARM Cortex processor and Bluetooth Low-Energy 4.0 built-in, which take your projects to the next level!

-Powerful enough to run your projects.
-Small enough to fit inside your projects.
-Low cost enough to be used for all your projects.

It's perfect for the hobbyist creating do-it-yourself projects, to professional engineers producing proof-of-concept prototypes.

It can be used with or without Bluetooth 4.0.

Beginners can use the pre-written Arduino sketches and advanced users can write their own from scratch.

We have several open-source RFduino and iPhone apps which are free to use, extend and share.

Stackable Shield Accessory Boards

The RFduino has been constructed with high quality, leading edge, state-of-the-art professional grade components.

We have also developed a few miniature accessory boards to help you with your projects.  They plug directly into 0.100" (2.54mm) standard spacing, solderless breadboards or run fully stand-alone.  They are stackable and plug directly into each other to provide many combinations.

    Is the chip single-mode bluetooth 4.0 or dual-mode? What does "It can be used with or without Bluetooth 4.0" mean?

    Single mode = It supports Bluetooth 4.0 only, no legacy 2.0, 2.1 or 3.0.
    Without = You can use it as a "Arduino kind of clone",
