Questions
How big is the Module PCB?
It measures 99.1 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Module use?
71 parts, built around the B10K. 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 Module KiCad files?
From the zlosynth/kaseta repository on GitHub, at the commit this page was made from: the board is hardware/Module.kicad_pcb and its schematic hardware/Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Module design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
