Controls:

  • We currently have planned to have three ~5 unique custom PCBs under our domain.:

    • Controls Leader SOM (LSOM) - 1

    • Controls Peripherals (PSOM) will handle: - 6 PSOMs

      • Lights Daughter, 5 PSOMs

      • Pedals Daughter, 1 PSOM

    • Network Switch for PoE

  • Other relevant pieces of hardware:

    • Prohelion Wavesculptor 22 Motor Controller: 14kw max output, 140V max input

      • Note: this is referenced throughout our software as the Tritium Wavesculptor, because Tritium used to own the product before Prohelion bought out that company.

      • Datasheet

      • User Manual
