Galileo Board
1.0 Overview
The Intel® Galileo Board provides a programmable control PCB for the maker
community , students, and professional developers. It is based on the Intel
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.

Table 1. Description of Key Components (Sheet 1 of 2)
Number Component Description
1 Ethernet Port 10/100 Ethernet connector
2 RS-232 Serial Port 3-pin 3.5mm jack (not audio)
3 RS-232 RS-232 transceiver
4 USB 2.0 Client
5 USB 2.0 Host
6 SPI Flash
7 SPI Flash Program Port
8Shield Interface
9 ADC Analog to Digital converter
USB Client connector (Micro-USB Type B): a fully compliant USB 2.0
Device controller, typically used for programming
USB 2.0 Host connector (Micro-USB Type AB): supports up to 128 USB
end point devices
8 MByte Legacy SPI Flash to store the firmware (or bootloader) and the
latest sketch.
7-pin header for Serial Peripheral Interface (SPI) programming
Defaults to 4 MHz to support Arduino Uno shields. Programmable up to
25 MHz.
Note: The board has a native SPI controller, however, it will act as a
master and not as an SPI slave. Therefore, it cannot be a SPI
slave to another SPI master. It can act, however, as a slave
device via the USB Client connector.
Complies with Arduino Uno Revision 3 shield pinout. See Section 2.4 for
details.
