Questions
How big is the Esc PCB?
It measures 35.5 × 62.5 mm and has 8 copper layers, 1.6 mm thick.
What parts does the Esc use?
67 parts, built around the STM32G071KBU6, DRV8300DPWR-MS, TSC213ICT and IPT017N10NM5LF2ATMA1. 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 Esc KiCad files?
From the FBIopeningUPP/BeastDrive repository on GitHub, at the commit this page was made from: the board is hardware/esc/esc.kicad_pcb and its schematic hardware/esc/esc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esc design in my own project?
Its repository states no licence, so its author keeps all rights: ask FBIopeningUPP before reusing the design.
