The QCard packs a programmable computer, up to 1megabyte of memory, communications, analogue and digital I/O, and an expansion I/O bus onto a tiny low-cost board.
To meet the demand for cost-effective, compact, yet powerful and expandable embedded controllers, Mosaic Industries Inc has introduced the QCard, a tiny 2x2.5inch single board computer that fits any hand-held or space-constrained applications and dramatically cuts the cost of data acquisition and control for OEMs.
The I/O-rich QCard hosts a 16MHz Motorola 68HC11F1 microprocessor, 512K Flash and 128K Ram (expandable to 512K), and 320 bytes of EEPROM.
On-board I/O includes eight digital I/O lines with counter/timer capabilities, eight analogue inputs, a fast synchronous SPI serial interface, and dual RS232/485 ports.
An optional real-time clock tracks the calendar and time of day and battery backs the 128K Ram.
The QCard is easily programmable in C, Forth or Assembly using any PC.
Built-in programming tools include an interactive debugger, a multitasking executive, and comprehensive device-driver libraries.
Convenient connectors allow for simple mechanical integration.
The QCard can directly host up to four I/O expansion modules called Wildcards that can be mixed and matched depending on the application.
The easy to use Wildcards stack onto the 24 pin Wildcard connector on the QCard.
A convenient PowerDock module includes an efficient switching power regulator and expands the Wildcard bus to host up to eight Wildcards.
Wildcards implement a wide variety of user interface, communications, data acquisition and control capabilities.
Available Wildcards include a keypad/display module, octal 12-bit D/A and 16-bit A/D converters, a 24-bit resolution analogue data acquisition subsystem, Compact Flash card mass memory interface, fast buffered RS232/485 dual UART, high voltage/high current isolated I/O, and AC or DC solid state relays.
Pricing starts at $149 for a single unit with considerable quantity discounts.
