KiCAD Projects: STRF 2.4GHz RF-to-USB Dongle by pms67

15 Aug, 2022

This KiCAD projects is STM32L4-based RF-to-USB dongle using a low-power NRF24 2.4GHz transceiver.

See the video to overview 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!)

Design files can be downloaded via the link below:
