Questions
How big is the MotorDriver PCB?
It measures 26.5 × 57.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MotorDriver use?
50 parts, built around the DWM1000, ESP32-WROVER-I, BMP280 and ISL9110IRT7Z-T7A. 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 MotorDriver KiCad files?
From the Kmshanley/MiniRobots repository on GitHub, at the commit this page was made from: the board is Motor Driver PCB/MotorDriverRev2/MotorDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MotorDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kmshanley before reusing the design.
