Intel Galileo

Product description
Galileo is a microcontroller board based on the Intel Quark SoC X1000 Application Processor, a 32-bit. It is the first board based on Intel architecture designed to be hardware and software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), Analog inputs 0 to 5, the power header, ICSP header, and the UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3. This is also known as the Arduino 1.0 pinout.
Galileo is a microcontroller board based on the Intel? Quark SoC X1000 Application Processor, a 32-bit Intel Pentium?-class system on a chip (SoC).
