A low cost C-programmable 68HC11 microcontroller based single board computer for embedded control
The QCard™ is a Single Board Computer (SBC) that packs a microcontroller, up to 1 megabyte of memory, communications, analog and digital IO (input/output), and an expansion IO bus on a tiny low-cost board. This 2" x 2.5" computer is perfect for space-constrained applications and dramatically cuts the cost of data acquisition and control. Easily programmed using either the C or Forth language, it is ideal for machine automation, industrial control, robotics, handheld data acquisition, and portable scientific instruments.
The IO-rich QCard hosts a 16 MHz Motorola 68HC11 microcontroller, 512K Flash and 128K RAM (expandable to 512K), and 512 bytes of EEPROM. On-board I/O includes 8 digital I/O lines with counter/timer capabilities, 8 analog inputs, a fast synchronous SPI serial interface, and dual RS232/485 serial 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. Embedded programming tools include an interactive debugger, a multitasking executive, and comprehensive device-driver libraries.
To communicate with the QCard via USB, order a USB to RS232 adapter and cable (see QCC-USB on Ordering page).
