Questions
How big is the PicoLink PCB?
It measures 53.2 × 24.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoLink use?
46 parts, built around the RP2040, AP2112K-3.3 and CSTNE12M0GH5L000R0. 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 PicoLink KiCad files?
From the ErichStyger/mcuoneclipse repository on GitHub, at the commit this page was made from: the board is KiCAD/Projects/PicoLink/PicoLink.kicad_pcb and its schematic KiCAD/Projects/PicoLink/PicoLink.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoLink design in my own project?
Its repository states no licence, so its author keeps all rights: ask ErichStyger before reusing the design.
