Questions
How big is the Pcb lab PCB?
It measures 118 × 250 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pcb lab use?
285 parts, built around the STM32F401RET6, SN65HVD230DR, ACS712ELCTR-05B-T and L298P. 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 Pcb lab KiCad files?
From the y-watal/pcb_lab repository on GitHub, at the commit this page was made from: the board is pcb_lab.kicad_pcb and its schematic Cockpit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb lab design in my own project?
Its repository states no licence, so its author keeps all rights: ask y-watal before reusing the design.
