SAMWISE Avionics Repository

Welcome to the SAMWISE GitHub Avionics repository! Here, we (try to) keep the most updated versions of all of our circuit boards accessible to the public.

General Layout

Individual boards have their own folders to ease merging of branches. Symbol libraries, footprint libraries, and 3D models are in separate top-level folders.

List of Relevant Boards (in alphabetical order of folder name)

Note that each major revision generally indicates a new satellite or a significant overhaul of the board and each minor revision generally indicates a board order.

Guidelines

1. Set up KiCad and GitHub according to the guides on the Sats AV Notion page.
2. ALWAYS check via git status and pull via git pull BEFORE making edits. If going into someone else's branch or main, use git restore <file> to restore changes before returning to your branch and do NOT commit/push changes without the branch owner's explicit permission.
3. Create your own branch when making edits. Make pull requests when you have finalized your changes. Do NOT push to main unless you are an AV or team co-lead.
4. To prepare your board for ordering, follow the Board Review and Ordering Procedures linked on the Notion page. This saves AV/team leads a substantial amount of time, and keeps things consistent/easy to review.
5. Do not edit this README unless you are an AV or team co-lead.
