    ® The Intel Galileo Board is 10 cm long and 7 cm wide respectively, with the USB connectors, UART jack, Ethernet connector, and power jack extending beyond the former dimension. Four screw holes (4 mm diameter) allow the board to be attached to a surface or case.
  • Page 9: Arduino Connector Pinout Details

    Galileo Board complies with the Arduino Uno Revision 3 pinout as follows: • 14 digital input/output pins (IO2-IO13, TX, RX): — Each of the 14 digital pins on Galileo can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
  • Page 10: Properties Of Pins Configured As Output

    Pins configured as OUTPUT with pinMode() are said to be in a low-impedance state. On ® the Intel Galileo Board, when a pin is configured as OUTPUT, the functionality is provided via an I C*-based Cypress I/O expander. Digital pins 0 to 13 and Analog pins ®...

    ® Details and Specifications—Intel Galileo Board Figure 4. Jumper Locations 2.5.1 IOREF Jumper To support both 3.3 V and 5 V shields, the external operating voltage is controlled via a jumper. • When the jumper is connected to 5 V, the board is configured to be compatible with 5 V shields and IOREF is set to 5 V.
  • Page 14: Vin Jumper

    ® If your Intel Galileo Board is in an unbootable state, you can force recovery to recover the contents of the SPI flash. For example, if power was lost during a normal firmware update, the board would be unbootable and this procedure would be necessary. You will need to ground a resistor pin as described below.

    ® Details and Specifications—Intel Galileo Board 6. The serial console displays a list of Quark platforms. Select Galileo. 7. The serial console displays a user action menu. Disconnect the resistor pin shown Figure 5 from ground. Select the system recovery option.
  • Page 16: Communication And Programming

    ® The Intel Galileo Board is the first Arduino board to provide a mini PCI Express* (mPCIe*) slot. This slot allows full size and half size (with adapter) mPCIe* modules to be connected to the board and also provides an additional USB Host port via the mPCIe* slot.
  • Page 17: Programming

    Rather than requiring a physical press of the reset button before an upload, the Intel Galileo Board is designed in a way that allows it to be reset by software running on a connected computer. USB CDC-ACM control signals are used to transition the board from run-time to bootloader mode.
