Questions
How big is the STEP MOTO PCB?
It measures 75 × 46.4 mm and has 4 copper layers, 1.61 mm thick.
What parts does the STEP MOTO use?
83 parts, built around the ESP-12F, DRV8711DCP, LM5575MH and CSD88537ND. 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 STEP MOTO KiCad files?
From the YIN0622/STEP_MOTO_PCB repository on GitHub, at the commit this page was made from: the board is STEP_MOTO.kicad_pcb and its schematic STEP_MOTO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STEP MOTO design in my own project?
Its repository states no licence, so its author keeps all rights: ask YIN0622 before reusing the design.
