KiCad STM32 + RF + USB Hardware Design - Phil's Lab #5

⏵Hardware and PCB design course: https://www.phils-lab.net/courses Overview of STM32, RF, and USB hardware design, schematic creation, and PCB layout and routing in KiCad using a real-world example project. (Timestamps in description) Various tips on controlled impedance routing, differential pairs, USB, and RF layout.
