Questions
How big is the LoPoPad PCB?
It measures 99.5 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoPoPad use?
60 parts, built around the RP2040-ZERO, 1N4148W and SK6812. 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 LoPoPad KiCad files?
From the mazestd/LoPoPad repository on GitHub, at the commit this page was made from: the board is hardware/LoPoPad.kicad_pcb and its schematic hardware/LoPoPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoPoPad design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
