The LaserBox Mux Board controls 36 lasers off three I/O pins, using shift registers. It has 6 separate channel connectors, each with 8 output pins on it.

Rev001 Issues

  • Bypass capacitors missing from BOM
  • Connectors provide a GND pin for each I/O pin, but the I/Os are sinks! Need +5V and I/O really.
    • Too late to re-spin the board, the connectors do provide one +5V pin so I'll have to work around the bug with creative cable building.
