Questions
How big is the Lab Sensor PCB?
It measures 94.3 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab Sensor use?
31 parts, built around the ESP32-POE, AM2302 and INMP441. 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 Lab Sensor KiCad files?
From the Siddarth-Kota/PCB-Projects repository on GitHub, at the commit this page was made from: the board is Lab_Sensor/Lab_Sensor.kicad_pcb and its schematic Keyboard/Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask Siddarth-Kota before reusing the design.
