Questions
How big is the Slab40 PCB PCB?
It measures 247.6 × 85.8 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Slab40 PCB use?
87 parts, built around the RP2040-TINY and 1N4148W. 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 Slab40 PCB KiCad files?
From the coffeebreak-chicken/40RowStaggered repository on GitHub, at the commit this page was made from: the board is KiCAD/PCB/Slab40_PCB.kicad_pcb and its schematic KiCAD/PCB/Slab40_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Slab40 PCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
