Questions
How big is the Pcb v3 PCB?
It measures 80 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb v3 use?
21 parts, built around the NODEMCU-32SLUA, TCRT5000 and ULN2003A. 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 v3 KiCad files?
From the 2026MakerClub/PCB repository on GitHub, at the commit this page was made from: the board is pcb_v3/pcb_v3.kicad_pcb and its schematic pcb_v3/pcb_v3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb v3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 2026MakerClub before reusing the design.
