Entire step-by-step process going through the design of STM32-based hardware in KiCAD, from schematic creation, through to four-layer PCB layout and routing, as well as sending it off for manufacture and assembly via JLCPCB (jlcpcb.com/RHS).

Minor correction: At around 23:35 I say the crystal load caps are in parallel. I meant to say, from the crystal’s ‘point of view’ the caps are in series and thus the capacitance seen by the crystal is halved. Further details: en.wikipedia.org/wiki/Pierce_...
