This repository details an investigation conducted by Mishay Naidoo for his EEE4022S Final year engineering project. The aim of the project was to design a traffic monitoring system using a low-cost Doppler radar. This project was done under the supervision of Prof. Amit Mishra of the University of Cape Town.
There is a pdf of the report describing the entire project in detail. The code used in the report is located in the Algorithms folder. The images generated using code are located in the ReportPlots folder. The extras folder just includes all of the files used when working on this project. All of the important files are in the other two folders.

Questions
How big is the STM32L4 Project PCB?
It measures 71 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32L4 Project use?
39 parts, built around the STM32L432KBU6, LM386, USBLC6-2SC6 and XC6206P332MR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the STM32L4 Project KiCad files?
From the MishayNaidoo/Traffic-Monitoring-Using-Doppler-Radar repository on GitHub, at the commit this page was made from: the board is PCB/STM32L4_Project/STM32L4_Project.kicad_pcb and its schematic PCB/ADC_Board/ADC_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32L4 Project design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
