The Phidget SBC4 is a Single Board Computer with six integrated VINT ports. VINT Ports can be used in one of four ways: Communicating with an intelligent VINT Device, reading a 0-5V Voltage or ratiometric sensor, acting as a digital output, or reading switches as a digital input. The SBC4 is an embedded computer that runs Debian GNU/Linux. It's useful for long-running Phidgets applications or projects that need to be more portable. You can connect a keyboard and monitor to work directly on the Phidget SBC using the pre-installed Linux terminal, or you can use an external computer to set up and run custom applications through the SBC's web interface. You can even use the SBC4 as a remote server, accessing Phidgets connected to your SBC from programs running on other computers or devices on the network.
