README
README.mdMy PCB Design Journey
Welcome! This repository is a living document of my hands-on journey into the world of PCB design and practical electronics using KiCad.
For me, this isn't just about connecting dots on a screen or getting an LED to blink. It’s about deeply understanding what happens beneath the surface—mastering current flow, grounding, return paths, routing strategies, and designing for actual manufacturability.
Instead of blindly copying tutorial schematics, I build these projects from the ground up using datasheets, engineering research, messy experimentation, and iterative redesigns based on real-world feedback.
The Toolkit
- Design: KiCad 10
- Version Control: Git & GitHub (because breaking things is part of the process)
- Validation: Rigorous DRC/ERC workflows
- Knowledge Base: Deep-dives into datasheets & community code reviews

Questions
How big is the ESP32 - LED Strip Driver PCB?
It measures 112 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 - LED Strip Driver use?
29 parts, built around the ESP32-WROOM-32D, LM2596S-3.3 and IRLB8721PBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32 - LED Strip Driver KiCad files?
From the yash-workspace/PCB-Projects repository on GitHub, at the commit this page was made from: the board is Project_2_ESP32_Driver/PCB/ESP32 - LED Strip Driver.kicad_pcb and its schematic Project_01_LED_Driver/schematic/LED_Driver_V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 - LED Strip Driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask yash-workspace before reusing the design.
