Introduction
Overview
The PhidgetSBC2 is a Single Board Computer with an integrated
PhidgetInterfaceKit 8/8/8. At its most basic, it can be thought
of as a Phidget that you connect using a network cable instead
of USB. The PhidgetSBC2 also provides six full-speed ports
that allow you to use normal USB Phidgets over its network
connection. This can extend the effective range of a Phidget
from USB’s maximum of 15 feet, to anywhere that your network
reaches.
The PhidgetSBC2 exposes an easy to use interface for setting
up and running custom applications on-board. This allows the
PhidgetSBC2 to operate autonomously, without the need for a
graphical interface or a remote connection at all times.
For more advanced users, the PhidgetSBC is an embedded
computer that runs Debian GNU/Linux. We provide full shell
access via a built-in SSH server, access to the full Debian package
repository, and all of the standard command line tools expected
on a modern Linux system.
An integrated PhidgetInterfaceKit 8/8/8 allows you to connect devices to any of 8 analog inputs, 8 digital inputs and
8 digital outputs. It provides a generic, convenient way to interface your PC and PhidgetSBC with a wide variety of
devices and it operates exactly the same way as an external PhidgetInterfaceKit.

Programming Environment
Operating System: Custom Linux Distro, built using Buildroot
Programming Languages (APIs): C/C++, Java
Examples: Many example applications for all the operating systems and development environments above are
available for download at www.phidgets.com.
Note: AninternetbrowserisrequiredtousethecongurationGUI.
When controlling the PhidgetSBC remotely, you can use any Phidgets supported operating systems and languages:
Operating Systems: Windows 2000/XP/Vista, Windows CE, Linux, and Mac OS X
Programming Languages (APIs): VB6, VB.NET, C#.NET, C++, Flash 9, Flex, Java, LabVIEW, Python, Max/MSP,
and Cocoa.
Integrated InterfaceKit 8/8/8
The PhidgetInterfaceKit 8/8/8 allows you to connect devices to any of 8 analog inputs, 8 digital inputs and 8 digital
outputs.
Analog inputs
They are used to measure continuous quantities, such as temperature, humidity, position, pressure, etc. Phidgets
offers a wide variety of sensors that can be plugged directly into the board using the cable included with the sensor.
Here is a partial list of sensors currently available:
IRDistanceSensor IRReectiveSensor VibrationSensor LightSensor
Force Sensor Humidity Sensor Temperature Sensor Magnetic Sensor
Rotation Sensor Voltage Divider Touch Sensor Motion Sensor
Mini Joy-Stick Pressure Sensor Voltage Sensor Current Sensor
Slide Sensor
Digital Inputs
Digital Inputs can be used to convey the state of push buttons, limit switches, relays, logic levels, etc...
Digital Outputs
Digital Outputs can be used to drive LEDs, solid state relays (have a look at our SSR board), transistors; in fact,
anything that will accept a CMOS signal.
Digital outputs can be used to control devices that accept a +5V control signal.
With transistors and some electronics experience, other devices can be controlled, such as buzzers, lights, larger
LEDs, relays.

Connect the analog sensor to the analog1.
input port 4 using a Phidgets sensor
cable. The analog input ports are
numbered from 0 to 7 starting from the
left.
Connect one end of a wire to digital2.
input port 0 and the other end to
ground (labelled ‘G’ on the underside of
the board).
Connect the LED by inserting the long3.
LED wire into the digital output 7 and
the shorter wire into Ground.
Connect the power supply to the4.
PhidgetSBC2 using the barrel connector.
Connect the PhidgetSBC2 to your5.
network with an Ethernet cable.
Plug the wall adapter into an appropriate outlet. The red status indicator light located near the USB ports should
be lit if the unit is receiving power. The green LED located above the red LED indicates boot status. The green
LED will turn on and off once during boot and then turn back on when everything is running.
Other Phidgets can also be connected to the 1072 using a USB cable.6.
