Order Number: 329681-003US
o Note: While Galileo has a native SPI controller, it will act as a master and not as an SPI slave.
Therefore, Galileo cannot be a SPI slave to another SPI master. It can act, however, as a slave
device via the USB Client connector.
device via the USB Client connector.
UART (serial port) Programmable speed UART port (Pins 0 (RX) and 1 (TX))
ICSP (SPI) - a 6 pin in-circuit serial programming (ICSP) header, located appropriately to plug into
existing shields. These pins support SPI communication using the SPI library.
VIN. The input voltage to the Galileo board when it's using an external power source (as opposed to 5
volts from the regulated power supply connected at the power jack). You can supply voltage through this
pin, or, if supplying voltage via the power jack, access it through this pin.
o Warning: The voltage applied to this pin must be a regulated 5V supply otherwise it could damage
the Galileo board or cause incorrect operation.
5V output pin. This pin outputs 5V from the external source or the USB connector. Maximum current
draw to the shield is 800 mA
3.3V output pin. A 3.3 volt supply generated by the on-board regulator. Maximum current draw to the
shield is 800 mA
GND. Ground pins.
IOREF. The IOREF pin on Galileo allows an attached shield with the proper configuration to adapt to the
voltage provided by the board. The IOREF pin voltage is controlled by a jumper on the board, i.e., a
selection jumper on the board is used to select between 3.3V and 5V shield operation.
RESET button/pin
o Bring this line LOW to reset the sketch. Typically used to add a reset button to shields that block
the one on the board.
AREF is unused on Galileo. Providing an external reference voltage for the analog inputs is not
supported.
o
For Galileo it is not possible to change the upper end of the analog input range using the AREF pin
and the analogReference() function.
