Docking Panels and PowerDocks

mechanical and electronic platform for single board computer

Introduction to the Docking Panel

The Docking Panel™ provides a mechanical and electronic platform for Mosaic's single board computers: the QCard Controller and the PDQ Board, and for the modular I/O plug-in boards called Wildcards. Measuring only 4" x 2.5", the Docking Panel/SBC/Wildcard solution packs a lot of control and I/O capability into a compact form factor.

The combination of the Docking Panel, the QCard or PDQ Board, and the 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 Docking Panel hosts a 1 amp 5 volt switching power supply, dual DB-9 and optional dual DB-25 serial connectors, a power jack, a master power switch, plus the Controller Board's and Wildcards' interface connectors onto a compact card. The serial connectors, jack and switch are designed for easy mounting to an instrument back panel.

The Docking Panel mates with the programmable QCard or PDQ Board, providing these single board computers with clean regulated 5V power, and bringing out their dual serial ports to convenient connectors. The Docking Panel also hosts up to 8 Wildcards in two stacks of up to 4 Wildcards each.

mechanical and electronic platform for single board computerThe Slim PowerDock (p/n PDS) is ideal for space-constrained applications. It provides power and convenient connectors and switches for the QCard and for up to 4 Wildcards. Measuring just 2" x 2.5", it hosts a high-efficiency 1 amp 5 volt switching power supply, dual DB9 serial connectors, I/O connectors, a power jack, and a power switch.

The 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.
