Questions
How big is the Batteryboard PCB?
It measures 95.9 × 90.2 mm and has 2 copper layers, 1.57 mm thick.
What parts does the Batteryboard use?
42 parts, built around the IRF7458. 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 Batteryboard KiCad files?
From the pycubed/hardware repository on GitHub, at the commit this page was made from: the board is batteryboard-v01/batteryboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Batteryboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask pycubed before reusing the design.
