Questions
How big is the ServoLess PCB?
It measures 37.1 × 41 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ServoLess use?
88 parts, built around the ESP32-S3FN8, INA240A2PW, DRV8313PWP and TPS54202DDC. 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 ServoLess KiCad files?
From the Aiano/ServoLess repository on GitHub, at the commit this page was made from: the board is Hardware/ServoLess_v2/ServoLess.kicad_pcb and its schematic Hardware/ServoLess/BLDC_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ServoLess design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aiano before reusing the design.
