January 19, 2010 - The PDQ Board is a single board computer that dramatically cuts the cost of data acquisition and control. It has 1 megabyte of memory, communications, Motorola 68HCS12 processor, dozens of analog and digital I/O lines, and dual expansion I/O buses onto a compact 2.5" x 4" board. The PDQ Board is ideal for instrumentation, industrial control, automation, and data acquisition.It delivers 8 digital I/O lines with counter/timer capabilities, 8 pulse-width modulated (PWM) digital output signals, and 8 general purpose digital I/O lines.
Additional I/O includes sixteen analog inputs with 10-bit resolution, dual RS232/485 ports with speeds to 256 KBaud, and synchronous SPI and IIC serial interfaces. Any of the digital I/O ports can be configured for general purpose I/O, and the analog input lines can be configured as digital inputs. An optional battery-backed real-time clock reports the time and date.The PDQ Board can directly host up to eight I/O mezzanine modules called Wildcards that you can mix and match depending on your application. The easy to use Wildcards stack onto the dual 24 pin Wildcard connectors on the PDQ Board.
Wildcards implement a wide variety of user interface, communications, data acquisition and control capabilities. Available Wildcards include Ethernet, WiFi, GPS, 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, USB, fast buffered RS232/485 dual UART, high voltage/high current isolated I/O, and AC or DC solid state relays.
