Questions
How big is the Hpi baja PCB?
It measures 90.2 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hpi baja use?
19 parts, built around the LMR33640DDDA and AMS1117-3.3. 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 Hpi baja KiCad files?
From the slimcdk/hpi-baja repository on GitHub, at the commit this page was made from: the board is electronics/electronics.kicad_pcb and its schematic electronics/electronics.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hpi baja design in my own project?
Its repository states no licence, so its author keeps all rights: ask slimcdk before reusing the design.
