QCard™ - a tiny low cost single board computer for data acquisition and instrument control
A Tiny Yet Versatile Embedded Computer
The QCard™ packs a programmable computer, up to 1 megabyte of memory, communications, analog and digital I/O, and an expansion I/O bus on a tiny low-cost board. This 2" x 2.5" single board computer is perfect for space-constrained applications and dramatically cuts the cost of data acquisition and control. It is ideal for machine automation, industrial control, robotics, handheld data acquisition, and portable scientific instruments.
The I/O-rich QCard hosts a 16 MHz Motorola 68HC11F1 microprocessor, 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 option below).
Use Mosaic's EtherSmart Wildcard, a 2x2.5" modular board to web-enable your QCard. The Ethersmart Wildcard enables communications between your instrument and other computers or peripherals via a Local Area Network (LAN) using the standard packet-based Ethernet signaling protocol. Simply plug a standard Ethernet cable into the RJ-45 jack on the Wildcard, and your instrument can communicate with other computers on a Local Area Network (LAN). Want to go wireless? Use the WiFi Wildcard which implements a wireless interface via a Wireless Local Area Network (WLAN) using the standard 802.11b/g packet-based protocol. Your application program can send emails to alert other computers on the network when significant events occur. You can even "browse into" your instrument using any standard web browser running on an online PC to monitor the status of your instrument.
Convenient connectors allow for simple mechanical integration. Like all of Mosaic's embedded controllers with low cost A/D D/A, the QCard can directly host I/O expansion modules called the Wildcards™ that you can mix and match depending on your application. Up to four easy-to-use Wildcards can stack onto the 24 pin Wildcard connector on the QCard. A convenient Docking Panel™ - a 4"x 2.5" module includes an efficient switching power regulator and expands the Wildcard bus to host up to 8 Wildcards. For space constrained applications, cosnsider a Slim PowerDock. Measuring just 2" x 2.5", it hosts a high-efficiency 1 amp 5 volt switching power supply, dual DB9 serial connectors, I/O connectors, a power jack, a power switch, and hosts up to 4 Wildcards.
Wildcards implement a wide variety of user interface, communications, embedded data acquisition and control capabilities. Available Wildcards include GPS tracking, Ethernet and WiFi communications, Keypad/Display module, octal 12-bit D/A and 16-bit A/D converters, a 24-bit resolution analog 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. You can select the Wildcards that meet your needs to configure a cost-effective customized controller for your application.
