Questions
How big is the Lathecontrol v3 PCB?
It measures 99 × 79 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lathecontrol v3 use?
129 parts, built around the RP2040, LM358DR2GH, W25Q128JVSIQ and USBLC6-2SC6. 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 Lathecontrol v3 KiCad files?
From the mirkoruether/lathecontrol repository on GitHub, at the commit this page was made from: the board is v3_rp2040/board/lathecontrol_v3.kicad_pcb and its schematic v2_stm32/board/currentloop_output.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lathecontrol v3 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).
