My first PCB design project, created to learn the basics of PCB layout, schematic capture, and manufacturing.
This project is my first attempt at designing a printed circuit board (PCB).
The goal was to better understand how PCBs are made, starting from schematic capture in KiCad and moving into PCB layout and manufacturing preparation.
📌 Project Overview
- Tool Used: KiCad
- Board Type: 2-layer
- Purpose: Practice learning PCB design workflow
- Features:
- Basic schematic capture
- Component placement and routing

Questions
How big is the Section 2 Schematic PCB?
It measures 45.5 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Section 2 Schematic use?
32 parts, built around the AMS1117-3.3. 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 Section 2 Schematic KiCad files?
From the Gobind-Kailey/PCB-Designing- repository on GitHub, at the commit this page was made from: the board is Section 2 Schematic/Section 2 Schematic.kicad_pcb and its schematic Section 2 Schematic/Section 2 Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Section 2 Schematic design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gobind-Kailey before reusing the design.
