I Designed My Own Drone ESC From Scratch (and it actually works)

I designed a 4-in-1 ESC from scratch, ordered it from JLCPCB, and put it in a real drone. In this video I explain how brushless motors work, what back-EMF is, how gate drivers and bootstrap circuits work, and how all of this comes together in a custom PCB. Then I flew it. And stress tested it at full throttle until the battery died. Links: GitHub (schematics, PCB, BOM, gerbers): https://github.com/Just4Stan/Open-4in...
