 <div class="blog-content">
 Overview of STM32, RF, and USB hardware design, schematic creation, and PCB layout and routing in KiCad using a real-world example project. 

Various tips on controlled impedance routing, differential pairs, USB, and RF layout.

Correction in schematic: NRF24 IREF pin needs to be pulled low to GND via a 10k resistor (not to 3V3 as shown in the video!). Fix has been pushed to GitHub.
