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 a 32-bit ARC architecture core, both clocked at 32MHz. The Intel toolchain compiles your Arduino sketches optimally across both cores to accomplish the most demanding tasks. 
The Real-Time Operating Systems (RTOS) and framework developed by Intel is scheduled to be open sourced in March 2016. Until then, it's not possible to interface with it directly; only the Arduino core can do it via static mailboxes, so it can only accomplish a predefined list of tasks (interface with PC using USB, program the sketch into flash, expose Bluetooth LE functionality to sketch, perform PWM). The RTOS for Intel Curie is still under development and new functions and features will be released in the near future.

The 101 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®. 

In the Getting Started section, you can find all the information you need to configure your board, use the Arduino Software (IDE), and start to tinker with coding and electronics.

• Try out the integrated accelerometer and gyro and discover sensor fusion
• Count your steps using the advanced features of 101's accelerometer
• Monitor your heart rate using the Bluetooth Low Energy capabilities (BLE)
