A Journey Through Voltmeters and Ammeters

Overview

I. Project Description

This is a voltage and current meter designed for the "Voltage and Current Meter Training Camp".

Based on the LCSC CW32F030C8T6 development board, it represents
a comprehensive learning journey from zero to professional in voltage and current meter design. For details, please refer to https://oshwhub.com/li-chuang-kai-fa-ban/cw32-shu-zi-dian-ya-dian-liu-biao-kai-fa-ban-tao-jian II. Features Here are the main differences: 1. Power supply section: Reserved power supply for the tested power source, with jumper H1 . 2. Interface changed to XT30 for easier wiring. 3. Added INA181 amplification to increase the current measurement range. 4. Added I2C interface for future OLED display connection. III. Interface Description Test Video:
