Questions
How big is the Batteryboard PCB?
It measures 95.9 × 90.2 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Batteryboard use?
38 parts, built around the IRF7458, DFLS130L, IRLML2803 and TTDO-10KC8-3-1%. 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 daheehee/very_cool_board repository on GitHub, at the commit this page was made from: the board is batteryboard-v02b/batteryboard.kicad_pcb and its schematic batteryboard-v02b/batteryboard.kicad_sch. 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 daheehee before reusing the design.
