Who
- Daniel Puratich architecture, component selection, pm
- Shawn Yang schem n layout I think but hasn't started yet
What
- interface between Pixhawk GPIO ports and 12v rail to pump, float, and release solenoid
- extremely simple
  - Proof of Concept
- Probably a dual channel HSD for 12V?
  - https://www.digikey.ca/en/products/detail/texas-instruments/TPS4H160AQPWPRQ1/6175214
  - I put other options in the schem
What will not be included,
- why am i mentioning things that won’t be features?
  - need to keep it simple and safe to get a functional first rev out fast
  - maybe this and other things could be implemented in the future long term in a future project but we just aren’t here yet as a team
- no buck
  - external buck for 48V to 12V required for the first rev, one will be selected and linked below, plenty of options exist for this
- no CAN circuit
  - firmware is struggling with https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2555904119/CAN+Integration+2025?search_id=99d9c02e-7941-4ee2-82d0-2c122bfa0b60&additional_analytics=queryHash---7f978b8f92e6fafe064d9236a790a0a47e8e5cec2916cdb791a52078bd173393
