Questions
How big is the Reference design PCB?
It measures 104 × 83.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Reference design use?
31 parts, built around the AH49FNTR-G1, SI2342DS-T1-GE3-VB and RP2040-ZERO. 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 Reference design KiCad files?
From the parakeyt/parakeyt-docs repository on GitHub, at the commit this page was made from: the board is reference-design/reference-design.kicad_pcb and its schematic reference-design/reference-design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Reference design design in my own project?
Its repository states no licence, so its author keeps all rights: ask parakeyt before reusing the design.
