Based on the CW32 voltage and current meter of the [LCSC development board]

Overview

This is a training project from the LCSC CW32 development board voltmeter and ammeter project, a digital voltmeter and ammeter built based on the LCSC CW32F030.
Circuit Design: To minimize the size of the main voltmeter, surface-mount components were used in the circuit board design.

Case Design: The case was designed using SOLIDWORKS software. After assembly and verification, the model was exported as an STL file and printed using a 3D printer.

Finished Product Showcase:

Product Testing: Voltage measurement was demonstrated using a 3V button battery.
