Questions
What parts does the BatteryLongboardHeadLights use?
22 parts, built around the AP5724WG and BQ29700DSE. 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 BatteryLongboardHeadLights KiCad files?
From the msglazer/Longboard_Headlights repository on GitHub, at the commit this page was made from: the board is Battery_Powered_Headlights/BatteryLongboardHeadLights.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BatteryLongboardHeadLights design in my own project?
Its repository states no licence, so its author keeps all rights: ask msglazer before reusing the design.
