Questions
How big is the Burnwing PCB?
It measures 68.7 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Burnwing use?
75 parts, built around the BTS7030-2EPA, TPS70933QDBVRQ1, TSA063G43-250 and AONR21307. 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 Burnwing KiCad files?
From the CubeSource/Burnwing repository on GitHub, at the commit this page was made from: the board is Burnwing.kicad_pcb and its schematic Burnwing.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Burnwing design in my own project?
Its repository states no licence, so its author keeps all rights: ask CubeSource before reusing the design.
