Hackaday drafts
Drafts for hackaday.io project logs about rp569. Facts come from specification.md, docs/ and the repo history;
check numbers and the repository URL before publishing. Images: docs/images/ (3D renders, layer plots as PNG for
upload); docs/img/ holds older renders (v0.2) and figures.

Ideas for later logs: the generated KiCad workflow (one Python file → schematic, PCB, BOM); JLCPCB parts hunting without the LCSC API (jlcparts data); bring-up and first HSPI transfer once boards arrive.
