Current Snapshot
Electronics
- Manufacturing-ready PCB work is under
hardware/final/; archived board spins live underhardware/archive/. - The active stack covers protection Rev B, boost Rev C, buck Rev C, high-side OR-ing Rev A, compute Rev A, and final control Rev A.
Mechanical
- Modular CAD lives in
mechanical/assemblies/andmechanical/components/. - The rover uses field-serviceable wheel pods, aluminium extrusion rails, custom 3D-printed parts, and integrated mounts for electronics, sensors, and mechanisms.
Software
software/is the autonomy-ready rover software workspace for control, camera, perception, navigation, and system integration.hardware/pcb_testing_firmware/contains electronics bring-up and validation sketches only; it is separate from the final software stack.

Maintenance Notes
- Keep generated PCB outputs inside the relevant board revision folder.
- Update CAD references when board dimensions, connector orientation, sensor placement, or mounting details change.
- Keep editable CAD, exported review files, and assembly notes together.
- Keep PCB validation sketches separate from final rover software.
- Update this README when top-level folders move or new subsystem entry points are added.

Questions
How big is the Boost converter PCB?
It measures 73 × 44 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Boost converter use?
34 parts, built around the CSD18540Q5B. 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 Boost converter KiCad files?
From the Tim4769/Microver repository on GitHub, at the commit this page was made from: the board is hardware/archive/boost_manufacturing_rev_a/Boost converter-2026-01-21_080914/Boost converter.kicad_pcb and its schematic hardware/archive/boost_manufacturing_rev_a/Boost converter-2026-01-21_080914/Boost converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Boost converter design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tim4769 before reusing the design.
