Questions
How big is the Wireless macrokey PCB?
It measures 110.3 × 93.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wireless macrokey use?
25 parts, built around the ESP32-WROOM-32E and LM1117T-3.3. 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 Wireless macrokey KiCad files?
From the nggaaa/wireless-macrokey repository on GitHub, at the commit this page was made from: the board is wireless-macrokey.kicad_pcb and its schematic wireless-macrokey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wireless macrokey design in my own project?
Its repository states no licence, so its author keeps all rights: ask nggaaa before reusing the design.
