Questions
How big is the LegSensorBoard PCB?
It measures 68 × 42 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LegSensorBoard use?
76 parts, built around the STM32F302CCT6, TJA1042T/3/1J, MAX11254ATJ+T and LP5907MFX-3.3. 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 LegSensorBoard KiCad files?
From the craftit/DogBotV4Electronics repository on GitHub, at the commit this page was made from: the board is PCBs/LegSensorBoard/LegSensorBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LegSensorBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
