KiCad STM32 + USB + Buck Converter PCB Design and JLCPCB Assembly (Update)

Entire step-by-step PCB design process going through the schematic, layout, and routing of a 'barebones' STM32F4-based PCB including USB and a buck converter in KiCAD. All the way from schematic creation, through to four-layer PCB layout and routing, as well as sending it off for manufacture and assembly via JLCPCB. Visit https://jlcpcb.com for $2 for five 2-layer PCBs and $5 for five 4-layer PCBs.
This is an update from the original 'KiCad STM32 Hardware Design' video, including some additional tips and tricks, as well as a show of various assembled boards made by JLCPCB. Hopefully with much improved audio quality!
