WIP (not approved by Emech+Electrical, wanted to put on here for first draft of system diagram):
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.
Mitsuba Motor: Three-phase, 96V nominal (160V max), 2000 watt nominal (5000 watt max).
