The Dragonix VZ mainboard serves as target development system. It is also perfectly suitable as final target device in low volume designs.

Development kit including linux CD-Rom, mainboard and QVGA monochrome display with touch panel is available for 600 Euro.

Mainboard will be plugged onto the customized hardware. Design examples available from dragonix.openhardware.net.

• Runs uClinux 2.4 kernel (own distribution included, updates freely available).


• 100x100mm mechanical size with mounting holes for 2.5'' ATA disk.


• Motorola Dragonball 68VZ328/33MHz CPU clock.


• LCD controller for monochrome and color displays (up to 640x512 dots).


• 2 x 2MB of onboard flash (1MB reserved by the linux kernel, remaining 3MB can be used as flash disk). 32 MB of SDRAM.


• Altera ACEX 1k30-3 FPGA with 50 free pins. LArger 1k50 and faster speed grades available on request.


• Verilog reference code put under GPL. A 68VZ328 to wishbone brifge opens the door to free cores from www.opencores.org (for example including ATA PIO controller, 2x SPIs, 1xI2C, 32 GPIO pins, 2xethernet controller glue logic, 1xUSB controller gluelogic, 1k scratch RAM and 2x8 Bit interupt controller needs only 70% of the FPGA capacity). DMA cores are only possible trough FPGA scratch ram, because the 68VZ328 does not support external DMA. Free Quartus Web Edition and Leonardo design tools available from www.altera.com.


• 10Base-T ethernet controller with status LEDs onboard, one RS232C serial port (second port with CMOS levels, also IRDA compatible), two SPI interfaces.


• All important signals are broad out on two 100 pin connectors (e.g. address- and databus, glue logic to external devices can easily implemented by the FPGA)


• Wide operation range (Vin 9-30V) trough on board stepdown converter. All importent power supply voltages broad out (5V@2.5A, 3.3V@0.8A, 2.5V@0.8A).


• Digitally programmable LCD contrast voltage controller (+15 to +24.5V). Negative contrast voltages available on request. Display touch panel controller (12 bit ADC, may also be used as general purpose ADC).


• Second onboard watchdog and reset controller.


• Real time clock with battery backup and 96 bytes of SRAM.
