Questions
How big is the AirDAP PCB?
It measures 42.5 × 21.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AirDAP use?
79 parts, built around the ESP32-S3-MINI-1U-N8, TPS631000DRL, SN74LVC1T45DBV and LM66100DCK. 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 AirDAP KiCad files?
From the guolic1/AirDAP repository on GitHub, at the commit this page was made from: the board is circuit/AirDAP.kicad_pcb and its schematic circuit/AirDAP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AirDAP design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
