  • [REV0.0.2]
    • added testpoint for GPIO0
    • R16 and R17 connected in series
    • interchanged GPIO2 and GPIO12 functions because GPIO12 cannot be pulled high while in flash mode
    • added 100nF in parallel with R13 for better battery voltage level reading
    • adjusted the pin labels for better visibility

Questions

How big is the REV0.0.2 LUMUHR GS CARBON D4 PCB?

It measures 39.5 × 18 mm and has 4 copper layers, 1.6 mm thick.

What parts does the REV0.0.2 LUMUHR GS CARBON D4 use?

67 parts, built around the TS342A2P-WZ. 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 REV0.0.2 LUMUHR GS CARBON D4 KiCad files?

From the GroundStudio/GroundStudio_Carbon_D4 repository on GitHub, at the commit this page was made from: the board is Hardware/REV0.0.2 - Kicad6/REV0.0.2 LUMUHR_GS CARBON D4.kicad_pcb and its schematic Hardware/REV0.0.2 - Kicad6/REV0.0.2 LUMUHR_GS CARBON D4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the REV0.0.2 LUMUHR GS CARBON D4 design in my own project?

Its repository states no licence, so its author keeps all rights: ask GroundStudio before reusing the design.
