Arduino 101 & Genuino 101 are the ideal successor of the UNO, updated with the latest technologies. It recognises gestures, and features a six-axis accelerometer and gyroscope. Control your projects with your phone over Bluetooth connectivity!

A learning and development board that delivers the performance and low-power consumption of the Intel® Curie™ Module with the simplicity of Arduino at an entry-level price. 
It keeps the same robust form factor and peripheral list of the UNO with the addition of onboard Bluetooth LE capabilities and a 6-axis accelerometer/gyro to help you easily expand your creativity into the connected world. 
The module contains two tiny cores, an x86 (Quark) and an ARC, both clocked at 32Mhz. The Quark core runs ViperOS RTOS and helps the Arduino core to accomplish the most demanding tasks. It comes with 14 digital input/output pins (of which 4 can be used as PWM outputs), 6 analog inputs, a USB connector for serial communication and sketch upload, a power jack, an ICSP header with SPI signals and I2C dedicated pins. 
The board operating voltage and I/O is 3.3V but all pins are protected against 5V overvoltage. 

The Arduino 101 (USA only) and the Genuino 101 (outside USA) has been designed in collaboration with Intel®.
