From the project

Beginner PCB design collection built in KiCad — includes 5V Regulated Power Supply, 555 Astable Multivibrator, and BJT Astable Multivibrator circuits.

This repository showcases three foundational PCB design projects created using KiCad, focusing on analog and mixed-signal circuit design for beginners in electronics. Each project demonstrates schematic design, PCB layout, and practical circuit understanding.

This project implements a transformer-based 5V DC regulated power supply designed using the LM7805 voltage regulator IC. It converts 230V AC mains into a stable 5V DC output, suitable for powering logic circuits, sensors, and microcontrollers.
