Questions
How big is the Mz pcb guide PCB?
It measures 228.6 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mz pcb guide use?
107 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Mz pcb guide KiCad files?
From the bridgethaas/mz-pcb-guide repository on GitHub, at the commit this page was made from: the board is mz-pcb-guide.kicad_pcb and its schematic matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mz pcb guide design in my own project?
Its repository states no licence, so its author keeps all rights: ask bridgethaas before reusing the design.
