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. Link to the Wiki for onboarding info and general resources
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. Project templates (for starting out) and jobsets (for project export) are in other top-level folders. Unused, old boards are in the unused_boards folder.
KiCad Version: 9.0.1 ≤ V < 10.0
Exception: unused boards are version 8.X.X
List of Relevant Boards (in alphabetical order of folder name)

Guidelines
- Set up KiCad and GitHub according to the guides in the Wiki.
- ALWAYS check via
git statusand pull viagit pullBEFORE making edits. If going into someone else's branch or main, usegit restore <file>to restore changes before returning to your branch and do NOT commit/push changes without the branch owner's explicit permission. - 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.
- 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.
- Do not edit this README unless you are an AV or team co-lead.

Questions
How big is the FlexDeploySidePanels PCB?
It measures 406 × 215.5 mm and has 4 copper layers, 0.66 mm thick.
What parts does the FlexDeploySidePanels use?
131 parts, built around the LTC2051HS8#PBF, RB160MM-60TR and SFH 2430-Z. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the FlexDeploySidePanels KiCad files?
From the stanford-ssi/samwise-avionics repository on GitHub, at the commit this page was made from: the board is FlexDeploySidePanels/FlexDeploySidePanels.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlexDeploySidePanels design in my own project?
Its repository states no licence, so its author keeps all rights: ask stanford-ssi before reusing the design.
