Questions
How big is the ESC PCB?
It measures 44 × 44 mm and has 4 copper layers, 1.58 mm thick.
What parts does the ESC use?
91 parts, built around the STM32L412CBU6, IR2103STRPBF, USBLC6-2SC6 and 1N5819WS. 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 Flynsky/Aeolus repository on GitHub, at the commit this page was made from: the board is STM32_ESC/Hardware/ESC_V1/ESC.kicad_pcb and its schematic Groundstation/Hardware/GS_controller/Comkicad_sch.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 Flynsky before reusing the design.
