Questions
How big is the BLDC 4 PCB?
It measures 39 × 85 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BLDC 4 use?
165 parts, built around the SN65HVD232D, CPC1002N, DRV8302 and SS24. 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 BLDC 4 KiCad files?
From the FrogFairy/bldc-hardware repository on GitHub, at the commit this page was made from: the board is design/BLDC_4.kicad_pcb and its schematic design/BLDC_4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLDC 4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask FrogFairy before reusing the design.
