G1 Bus Breakout


Breakout board for the Dreamcast G1 Bus (what the GD-ROM drive is connected to).

Sub-project and Repository

The repository contains:

  • Altium Design Files
  • Bill of Materials
  • Schematic Prints
  • Draftsman Board Design Documents
  • Gerber Files
  • Licence Information


When getting the PCB manufactured make sure to use one of the tagged revisions in the repository, otherwise the board will probably not be functional. Although version 2.0 works I recommend waiting for the next revision.

Check the Draftsman documents for information on some of the manufacturing requirements for the PCB like size, stack up, drill sizes, etc..
