Until recently, PCB design was something that looked incredibly complicated to me. I used to see images of professionally designed circuit boards online and always wondered: “How do people actually make these?” This project became my first real attempt at understanding that process. Using a simple 2N2222 transistor audio amplifier circuit, I started learning how schematics become actual PCB boards using KiCad and EasyEDA. What seemed like a small beginner electronics project quickly became one of the most valuable learning experiences I’ve had so far. Starting With the Circuit The project was based on a simple transistor amplifier using the 2N2222 NPN transistor.…
