http://newsroom.intel.com/community/int ... d-studentsIntel Corporation CEO Brian Krzanich today announced a collaboration agreement with Arduino LLC, the leading open-source hardware platform in the maker and education community. Krzanich also unveiled the Intel® Galileo board, the first product in a new family of Arduino-compatible development boards featuring Intel® architecture.
http://arduino.cc/en/ArduinoCertified/IntelGalileoGalileo is a microcontroller board based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip (datasheet?). It’s 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.
I'm not totally sold if it doesn't have the Arduino Mega shield space.
