README
README.md仓库简介
本仓库计划托管墨项目中全部电机驱动器，包括每款电机驱动器的电路设计和软件源码。但目前只有一款，所以目录结构暂不复杂化。
仓库中的电路设计材料可以使用 KiCad 工具查看与编辑，请确保已经导入了 kicad-libraries 仓库中提供的外部库再打开项目文件。
驱动器的软件源码所需的编译工具链与下载工具会因电机驱动器硬件平台而异。

Questions
How big is the Motor controller PCB?
It measures 26 × 35.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motor controller use?
34 parts, built around the STM32F031C6T6, SSP7903P33PR and NCD0603W1. 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 controller KiCad files?
From the godgnidoc/moh-motor-controller repository on GitHub, at the commit this page was made from: the board is motor-controller.kicad_pcb and its schematic motor-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motor controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask godgnidoc before reusing the design.
