Questions
How big is the BioSensorBox PCB?
It measures 52.6 × 40 mm and has 4 copper layers, 1.61 mm thick.
What parts does the BioSensorBox use?
56 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3, MPU-6050 and SRV05-4. 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 BioSensorBox KiCad files?
From the JH2k00/BioSensorBox repository on GitHub, at the commit this page was made from: the board is biosensorbox/biosensorbox.kicad_pcb and its schematic biosensorbox/biosensorbox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BioSensorBox design in my own project?
Its repository states no licence, so its author keeps all rights: ask JH2k00 before reusing the design.
