Questions
How big is the Tutorial02 PCB?
It measures 39.3 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tutorial02 use?
17 parts, built around the ATMEGA328P-PU. 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 Tutorial02 KiCad files?
From the D76X/KiCad repository on GitHub, at the commit this page was made from: the board is Projects/Tutorial02/Tutorial02.kicad_pcb and its schematic Projects/KLP-5e-ESP32-sensor-board-01/KiCad project/ESP32 sensor board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tutorial02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask D76X before reusing the design.
