Voltmeter and Ammeter

This design is based on the hardware circuit design
training camp curriculum. I also designed the 3D shell and panel myself; please refer to the editor for details.
Software design
and code are based on the training camp project materials: https://wiki.lckfb.com/zh-hans/dwx-cw32f030c8t6/, or the attached code.

Materials should be purchased
according to the project BOM.
Copper eyelets are required; they are not available on the LCSC website and are used to easily insert probes.
Assembly instructions:
Beginners are advised to use a heating table with solder paste for soldering; it's simple and easy to learn (I used a constant temperature 250°C heating table and medium-temperature solder paste). (Be careful with the heating table after use; it gets very hot!)
The 3D shell and panel
files can be found in the exported project file;
the physical verification video
is attached.
