Questions
How big is the Lazy Mouse PCB?
It measures 46 × 124.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lazy Mouse use?
62 parts, built around the ESP32-WROOM-32, LM3671MF-3.3, EN10HT1212N5HH3 and MCP73833. 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 Lazy Mouse KiCad files?
From the WeBuildAnything/Wireless-Media-Control-Mouse repository on GitHub, at the commit this page was made from: the board is KiCad Files/Lazy Mouse.kicad_pcb and its schematic KiCad Files/Lazy Mouse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lazy Mouse design in my own project?
Its repository states no licence, so its author keeps all rights: ask WeBuildAnything before reusing the design.
