Questions
How big is the Blade PCB?
It measures 50 × 111 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Blade use?
118 parts, built around the CH340C, ESP32-S3-WROOM-1-N16, AMS1117 and AP2112K-1.8. 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 Blade KiCad files?
From the JosephStew-art/Blade-PCB repository on GitHub, at the commit this page was made from: the board is Blade.kicad_pcb and its schematic Blade.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blade design in my own project?
Its repository states no licence, so its author keeps all rights: ask JosephStew-art before reusing the design.
