Introduction
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?
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 CAN Integration 2025
