README
hardware/flash_adapter/README.mdFlash Adapter PCB
This KiCad project is intended to be exported for JLCPCB with KiCad 9.
Use KiCad 9 from your PATH:
kicad-cli versionThe expected version for the checked-in production files is KiCad CLI 9.0.9.
Generate JLCPCB Files
These commands follow JLCPCB's KiCad 9 Gerber/drill preparation guidance:
- Run DRC before generating manufacturing files.
- Export the standard fabrication layers: copper, paste, silkscreen, solder mask, and
Edge.Cuts. - Use Protel filename extensions for Gerbers.
- Use extended X2 format and include netlist attributes.
- Generate Excellon drill output with absolute origin, millimeters, decimal zeros format, and alternate oval-hole mode.
- Use the drill/place-file origin so Gerber, drill, and CPL coordinates are positive and board-relative.
- Format the BOM as
Comment,Designator,Footprint,JLCPCB Part #（optional）. - Format the CPL as
Designator,Mid X,Mid Y,Layer,Rotation, withmmcoordinate suffixes. - Zip only the Gerber layers and merged Excellon drill file before upload.

make jlcpcbThe Makefile stops before export if DRC errors or ERC violations are found.
It runs the sequence below. For an AppImage installation, override the command:

It measures 35 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E73-2G4M08S1C-52840 use?
28 parts, built around the E73-2G4M08S1C, TS-1187A-B-A-B, AFC20-S02ACA-00 and FTSH-105-01-L-DV-K-TR. 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 E73-2G4M08S1C-52840 KiCad files?
From the Rogger/schneggi-sensor repository on GitHub, at the commit this page was made from: the board is hardware/base/E73-2G4M08S1C-52840.kicad_pcb and its schematic hardware/base/E73-2G4M08S1C-52840.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E73-2G4M08S1C-52840 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
