Fairly random collection of designs related to my hobbies, with backup in hidden agenda. Historic items are in PCB123 (private vendor-specific, incompatible with anything else); more recent work is KiCad and LtSpice.

SeanP2001/Urumbu_USB_Stepper_Motor
A modular approach to prototyping machines that move in the FabLAB
It measures 57.4 × 48.5 mm and has 2 copper layers, 1.6 mm thick.
52 parts, built around the ATSAMD11C14A-SSN, MAX4230AXK, MC74VHC1GT14DF and MIC1555BM5. 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.
From the Secoh/Electronics repository on GitHub, at the commit this page was made from: the board is MCU/D11/starter_d11_rev2/starter_d11_rev2.kicad_pcb and its schematic MCU/D11/starter_d11/starter_d11.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
