Questions
How big is the Leanometer esp32 PCB?
It measures 91.3 × 63.8 mm and has 4 copper layers, 1.56 mm thick.
What parts does the Leanometer esp32 use?
75 parts, built around the ESP32-WROOM-32D, DM3AT-SF-PEJM5, 74HC595 and MPU-6050. 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 Leanometer esp32 KiCad files?
From the theloukou/ESP32_leanometer repository on GitHub, at the commit this page was made from: the board is PCB/leanometer_esp32.kicad_pcb and its schematic PCB/DisplayBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leanometer esp32 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
