I put other options in the schem
What will not be included initially, m a y b e in a future rev
no buck to keep it simple, external buck for 48V to 12V required
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
