Questions
How big is the Datalogger PCB?
It measures 55 × 30.3 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Datalogger use?
49 parts, built around the ESP32-C3-MINI-1-N4, BME280, CP2102-GM and MSD-1-A. 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 Datalogger KiCad files?
From the TinoCoda/sensor-node repository on GitHub, at the commit this page was made from: the board is Datalogger.kicad_pcb and its schematic Datalogger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Datalogger design in my own project?
Its repository states no licence, so its author keeps all rights: ask TinoCoda before reusing the design.
