PowerDockTM

mechanical and electronic platform for QCard single board computer










Introduction to the PowerDock

The PowerDockTM provides a mechanical and electronic platform for the QCard Controller and Wildcards. Measuring only 2 x 2.5" for the slim version, or 4” x 2.5” for the standard version, the PowerDock/QCard/Wildcard solution packs a lot of control and I/O capability into a compact form factor.

The combination of the PowerDock, QCard Controller, and I/O Wildcards provides a custom off-the-shelf solution for instrumentation and control applications that require an embedded computer and a customized complement of analog, digital and communications I/O. The PowerDock hosts a 1 amp 5 volt switching power supply, dual DB-9 serial connectors, a power jack, a master power switch, plus QCard and Wildcard interface connectors onto a compact card. The serial connectors, jack and switch are designed for easy mounting to an instrument panel.

The PowerDock mates with the programmable QCard Controller, providing it with clean regulated 5V power, and bringing out the QCard’s dual serial ports to convenient connectors.

The slim version of the PowerDock hosts a QCard plus up to 4 Wildcards. The standard PowerDock hosts a QCard plus up to 8 Wildcards in two stacks of up to 4 Wildcards each.

Wildcards implement a wide variety of user interface, communications, data acquisition and control capabilities.

You can select the Wildcards that meet your needs to configure a cost-effective customized controller for your application. If you need something special, we’ll work with you to customize Wildcards for your volume application.
