CW32 voltage and current meter (STM32 compatible)

Overview

Compared to the official project: 1. A CH340N serial port has been added, enabling communication with the microcontroller via USB for convenient data acquisition; 2. A WS2812 LED has been added, allowing for more visually appealing designs;
3. Six NPN transistors are used to drive the digital tube, reducing the microcontroller's current consumption;
4. ESD protection has been added to the interface to enhance electrostatic discharge protection;
5. The digital tube adopts a common anode design.
