For use in instrumentation and automation applications, Mosaic Industries (Newark, Calif.) is rolling out its QCard single board computer. This 2 x 2.5-in. board is for handheld and space-constrained applications.
Smaller than a credit card, the QCard sports a 16-MHz Motorola 68HC11F1 microprocessor, 512 kbytes of flash, and 128 kbytes of RAM. It also includes 320 bytes of EEPROM, eight lines of programmable I/O, and built-in analog-to-digital conversion. For communications, the board includes dual RS-232/RS-485 ports.
The QCard is also programmable in C and Forth, or assembler, using any PC. Built-in programming tools feature an interactive debugger, a multitasking executive, and device-driver libraries.
The board is also modularly expandable. Modules include a 4-line x 20-character display, a 5-column x 4-row keypad, and 240 x 128-pixel backlit graphic display, and a touchscreen. The system includes a 16- or 24-bit resolution A/D, a 12-bit D/A, and isolated AC or DC solid-state relays.
Connectors support mechanical integration of the modules. The QCard can directly host up to four I/O expansion modules called Wildcards. You can mix and match Wildcards for your application. The Wildcards stack onto a 24-pin Wildcard connector on the QCard.
There's also a so-called PowerDock module. It includes a switching power regulator and expands the Wildcard bus to host up to eight Wildcards. Wildcards implement a variety of user interface, communications, data acquisition, and control capabilities.
Pricing starts at under about $120 a pop in quantities of 100. For more information contact Elena Belkine at Mosaic Industries, Newark, Calif. Phone: 510-790-8222
