This article focuses on how the Arduino Development Board works from a hardware perspective.
Most of the articles are about Arduino software. However, an in-depth understanding of its hardware design can help you take a solid step in the Arduino journey. Mastering the electronic design of the Arduino hardware will help you learn how to embed Arduino into the design of your final product, including which parts should be retained from the original design and omitted. Component Overview
The design of the Arduino UNO Development Board is all based on the use of SMD (Surface mount device) components. A few years ago, when I was learning about the Arduino PCB design, I started to understand the SMD components, and I was re-designing an Arduino Uno clone version.
Integrated circuits are packaged in a standardized package and are available in a variety of packaging formats.
The dimensions of many SMD resistors, capacitors, and LEDs are indicated by the following package codes:
