🔧 Arduino-Nano-Compatible-PCB-Design

📌 Project Overview

This repository contains the schematic and PCB layout design of an Arduino Nano–compatible development board. The project focuses purely on PCB design practices, including schematic capture, component footprint selection, 2-layer PCB layout, and layer stackup definition using professional EDA tools. No firmware development or physical hardware assembly was performed as part of this project.
