Questions
How big is the MINI SERVER BATTERY PCB?
It measures 28 × 10 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MINI SERVER BATTERY use?
66 parts, built around the ATMEGA328P-AU, XC9141A50DMR-G, DW01A and L7805. 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 MINI SERVER BATTERY KiCad files?
From the G-Deni/Smart-Battery repository on GitHub, at the commit this page was made from: the board is MINI-SERVER-BATTERY/MINI-SERVER-BATTERY.kicad_pcb and its schematic MINI-SERVER-BATTERY/MINI-SERVER-BATTERY.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MINI SERVER BATTERY design in my own project?
Its repository states no licence, so its author keeps all rights: ask G-Deni before reusing the design.
