Questions
How big is the Hbridge breakout PCB?
It measures 28.5 × 38.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hbridge breakout use?
15 parts, built around the DRV8870DDA and 74HC00D. 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 Hbridge breakout KiCad files?
From the CapnKernel/hbridge-breakout repository on GitHub, at the commit this page was made from: the board is hbridge-breakout.kicad_pcb and its schematic hbridge-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hbridge breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask CapnKernel before reusing the design.
