LCSC Voltmeter and Ammeter Training Camp

Overview

This is the first PCB board I've built since I started learning embedded hardware. Experiencing LCSC's PCB manufacturing and color silkscreen printing services is fantastic!

On the hardware side, this is my first time trying to build a project from scratch, starting with drawing the schematic. There are still many issues with the PCB design. On

the software side, besides displaying the acquired voltage and current values, it also has a software calibration function. The above demonstration shows the voltage calibration function. (Since my main goal is to learn hardware knowledge, the software is written relatively simply, focusing on achieving the required functionality.)

Thoughts shared by an RF engineer
Ten years have passed, but I still have nothing. Looking back, I feel so desolate. Because of my low education, I cannot enter well-known enterprises. Only some small companies hire me because of my r
Sigh, I just did something evil
1. Blocked a person who posted illegal ads; 2. Caught a person who was posting pure water to earn points, and deleted all the pure water. After deleting, this guy owed 31 core coins... No way :)
