• You can download and check the project in Kicad.
• You can order this board (incl. SMT assembly) at https://www.jlcpcb.com.
• Gerber and assembly files are in the relevant repo folders.

With this project you can learn how to design:

• Switching voltage regulator and Low-dropout regulator
• STM32 MCU that using USB & SPI interface
• ADC / DAC integration
• Creating kalman filter for noise
• Also how to isolate the part with PCB cutouts for noise

NOTE:If you are an employer , you can check out my skills...

Where can you use it?

• If you need many ADC or DAC readings, STM32 have limited number of ADC/DAC , such as if you design an SDD tester etc.
• If you need more accurate readings, I used 14-Bit for ADC and 12-Bit for DAC but you can go 16-BIT or more...
• ADC => (ADC141S626 14-Bit, 50 kSPS to 250 kSPS)
• DAC => (DAC7563SDGSR 12-Bit, 0 to 3.3V)
• I used these parts because I had at my invertory, but I think you get the idea.
• If you need filtering for noise, kalman filters are so common in industry. Drones etc. Don't forget the test with LTSPICE.
