Build

Schematic → PCB: kicad-cli sch erc → kicad-cli pcb drc.
Gerbers: File → Fabrication Outputs → Gerbers (X2) + Drill → zip B_Cu.gbr, F_Cu.gbr, Edge_Cuts.gbr … (see top-level FABRICATION.md pattern).
BOM / POS: Tools → Generate BOM (JLCPCB), Fabrication → Component Placement → pos.csv. Placeholder in BOM.md.

Pinout

Rows/cols map to nice_nano pins — verify in schematic vs ../../firmware/kmk/quickpin/pro_micro/nice_nano.py. Battery from P0_13/VBAT, power switch on RAW.

Known

Pre-split prototype — no TRRS/split connector (add split module later if needed).
Keep *.round-tracks-config in sync after moves.

Questions

How big is the Basic65 PCB?

It measures 303.2 × 93.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Basic65 use?

142 parts. 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 Basic65 KiCad files?

From the JonyBepary/secure-hid repository on GitHub, at the commit this page was made from: the board is hardware/basic65/basic65.kicad_pcb and its schematic hardware/basic65/basic65.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Basic65 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).
