Does

Guts

  • Driven by ATmega 328

Connection

  • Power
    • external 12v PSU

  • Analog
    • DA15 (15pins 2 rows)
    • Common ground on pin 15
    • channels on 1 to 6, 7 to 12
      • if soneone wants, they can then duplicate everything to get channels 7 to 12
  • DMX
    • 120ohm, 3 pole, XLR for each set of six.
      • because that means we don't have to play around with chaining.
      • Also, if one Universe fails, we still have the other to run on.
