Questions
How big is the Minilab PCB?
It measures 158.8 × 72.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minilab use?
96 parts, built around the NE555D. 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 Minilab KiCad files?
From the Enig17/Minilab repository on GitHub, at the commit this page was made from: the board is Minilab/Minilab.kicad_pcb and its schematic Minilab/Minilab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minilab design in my own project?
Its repository states no licence, so its author keeps all rights: ask Enig17 before reusing the design.
