Questions
How big is the ESP32-R7-Data Logger PCB?
It measures 150 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-R7-Data Logger use?
23 parts, built around the ESP32-WROOM-32UE-N4, SN65HVD230DR, DM3AT-SF-PEJM5 and ZX-XH2.54-4PWT. 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 ESP32-R7-Data Logger KiCad files?
From the davidrfloydii/ESP32-R7-Data-Logger repository on GitHub, at the commit this page was made from: the board is EDA/esp32-r7-data-logger/esp32-r7-data-logger.kicad_pcb and its schematic EDA/esp32-r7-data-logger/esp32-r7-data-logger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-R7-Data Logger design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidrfloydii before reusing the design.
