RFduino Bluetooth BLE - - compatible with Arduino

RFduino: A finger-tip sized, Arduino compatible, wireless enabled microcontroller, with built-in Bluetooth 4.0 Low Energy. Easy to use Arduino IDE & sketches running on professional grade hardware.

The RFduino runs Arduino code and can do everything an Arduino can, plus much more.

Using the RFduino USB shield, simply plug the RFduino into a USB port of any computer and use the Arduino IDE to load your Arduino sketch, which automatically begins running on the RFduino.

Then you can detach the RFduino USB shield and plug the RFduino directly into your project.

(The RFduino requires USB Shield part number RFD22121 for programming. You can select the RFD22121 USB Shield from the A La Carte items below or you can order a Kit which includes at least one RFD22121 USB Shield.)
