Questions
How big is the Shadow PCB?
It measures 69.9 × 78.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shadow use?
100 parts, built around the BQ24092DGQR and XB8089D. 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 Shadow KiCad files?
From the ym-ci/shadow-pcb repository on GitHub, at the commit this page was made from: the board is shadow.kicad_pcb and its schematic I2C_PINOUT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shadow design in my own project?
Its repository states no licence, so its author keeps all rights: ask ym-ci before reusing the design.
