The Qcard is a tiny 2 x 2.5in single board computer that fits any handheld or space-constrained application and dramatically cuts the cost of data acquisition and control for OEMs. The QCard packs a programmable computer, up to 1Mbyte of memory, communications, analogue and digital I/O, and an expansion I/O bus onto a tiny low-cost board. The I/O-rich QCard hosts a 16MHz Motorola 68HC11F1 microprocessor, 512Kbyte Flash and 128Kbyte RAM (expandable to 512Kbyte), and 320byte of EEPROM.

Onboard 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 128Kbyte 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 users can mix and match 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 12bit D/A and 16bit A/D convertors, a 24bit resolution analogue data acquisition subsystem, CompactFlash 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.
