Questions
How big is the Tuto kicad PCB?
It measures 48 × 38 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tuto kicad use?
46 parts, built around the STM32G431KBT6, ADXL343BCC, MIC5317-3.3YM5-TR and USBLC6-2SC6. 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 Tuto kicad KiCad files?
From the DRCDanilo/CommTrainer_PCB repository on GitHub, at the commit this page was made from: the board is tuto_kicad.kicad_pcb and its schematic stm32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tuto kicad design in my own project?
Its repository states no licence, so its author keeps all rights: ask DRCDanilo before reusing the design.
