Questions

How big is the Laser lipo PCB?

It measures 27.7 × 14.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Laser lipo use?

15 parts, built around the LP3985 and MCP73831. 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 Laser lipo KiCad files?

From the noahp/laser_lipo repository on GitHub, at the commit this page was made from: the board is hw/kicad/laser_lipo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Laser lipo design in my own project?

Its repository states no licence, so its author keeps all rights: ask noahp before reusing the design.
