Questions

How big is the Two motor driver PCB?

It measures 123.8 × 60 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Two motor driver use?

51 parts, built around the L6234PD and BAT54S. 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 Two motor driver KiCad files?

From the owhite/two_motor repository on GitHub, at the commit this page was made from: the board is kicad/two_motor_driver.kicad_pcb and its schematic kicad/two_motor_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Two motor driver design in my own project?

Its repository states no licence, so its author keeps all rights: ask owhite before reusing the design.
