BubbleBoard 

The BubbleBoard is a hardware development of the BalloonBoard; the architecture is largely unchanged:

  • Processing sub-system based on an XScale processor.
  • X-Scale 520 MHz PXA270; 256 Macrocell Coolrunner CPLD; 16Gb and 512Mb NAND16Mb NOR (Bootloader). 
  • Configurable I/O.
  • 16-bit SAMOSA bus.
  • USB (1.0, host and slave).
  • Product-embeddable design.
  • Low-power, single 5V supply.
  • RoHS compliant.
  • Open Hardware design. 
Handling:
Sit down; grip lightly by the board-edges; slip the board back into its anti-static bag if you need to walk with it.
In a production-situation, use an anti-static workstation. 
  • Attached: bus schematic, specification and test-points.
