Questions
How big is the Sensor Data Logger PCB?
It measures 83.8 × 41.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor Data Logger use?
73 parts, built around the ESP32-WROOM-32, MEM2051-00-195-00-A, AMS1117-3.3 and DS3231MZ+. 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 Sensor Data Logger KiCad files?
From the jminjares4/ESP32-Sensor-Data-Logger repository on GitHub, at the commit this page was made from: the board is hardware/Sensor Data Logger/Sensor Data Logger.kicad_pcb and its schematic hardware/Sensor Data Logger/Sensor Data Logger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor Data Logger design in my own project?
Its repository states no licence, so its author keeps all rights: ask jminjares4 before reusing the design.
