It is based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip. The Intel® Galileo Board is the first board based on Intel® architecture designed to be hardware and software pin-compatible with Arduino shields designed for the Uno R3. It is also software-compatible with the Arduino* Software Development Environment, making usability and development a snap. In addition to Arduino hardware and software compatibility, the Intel® Galileo Board has several industry-standard I/O ports and features to expand native usage and capabilities beyond the Arduino shield ecosystem, which are described in the next section of this document.
