Questions
How big is the Motor Driver Board PCB?
It measures 63.8 × 52.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motor Driver Board use?
36 parts, built around the XL1509-5.0, A4988, FXL1040-680-M and SS34. 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 Motor Driver Board KiCad files?
From the rdi-wang/Motor_Driver_Board repository on GitHub, at the commit this page was made from: the board is Hardware/Motor_Driver_Board.kicad_pcb and its schematic Hardware/Motor_Driver_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motor Driver Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask rdi-wang before reusing the design.
