Questions
How big is the BDCSC PCB?
It measures 75 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BDCSC use?
53 parts, built around the DRV8870DDA and LM358. 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 BDCSC KiCad files?
From the ToonVanEyck/BDCSC repository on GitHub, at the commit this page was made from: the board is hardware/src/BDCSC.kicad_pcb and its schematic hardware/src/BDCSC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BDCSC design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
