Questions
How big is the PCBWatch PCB?
It measures 45 × 75.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCBWatch use?
45 parts, built around the MBR0530 and BAT-HLD-001. 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 PCBWatch KiCad files?
From the tototmek/PCBWatch repository on GitHub, at the commit this page was made from: the board is PCBWatch.kicad_pcb and its schematic PCBWatch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCBWatch design in my own project?
Its repository states no licence, so its author keeps all rights: ask tototmek before reusing the design.
