The Keypad/Display WildcardTM

Tiny Card Adds an Interactive User Interface to Your Instrument

character display operator interface

The Keypad/Display WildcardTM provides a convenient interface to a 4 x 20 character display and 4 x 5 keypad. Combined with Mosaic's QCardTM Controller, it is an ideal solution for hand-held or space-constrained applications that require a programmable embedded computer and a low cost yet smart user interface.

Measuring only 2" x 2.5", the Keypad/Display Wildcard mounts directly on the QCard. The Keypad/Display Wildcard is shipped with a 4x20 character display and 4x5 keypad, plus a simple ribbon cable interface that enables custom placement of the keypad and display in your instrument. The Wildcard has an additional field header that brings out 4 nibble-wise programmable input/output lines and 4 input lines.

Add more I/O

You can add lots of "custom off-the-shelf" I/O to your system using Mosaic's diverse set of Wildcards. Wildcards are modular 2"x2.5" plug-in boards that you can mix and match to create your own custom system. They are ideal for applications requiring multiple I/O points, high resolution data acquisition, multi-channel communications, and real-time control.

When combined with the QCard Controller, the Keypad/Display Wildcard makes it easy to design interactive instruments with intuitive user interfaces.
