About the Arduino-Uno PCB

Arduino-Uno is an open source AVR/Arduino PCB design by MohamedHassanExp, published on GitHub under the MIT license. It is a 4-layer board measuring 59.9 × 66.5 mm, with 46 components from 31 distinct parts.

Its main chip is the ATMEGA328-P, from the AVR/Arduino family. Other key parts include the USBLC6-2P6, ATMEGA16U2-A, AMS1117-5.0 and AMS1117-3.3. By type, the board carries 12 capacitors, 12 resistors, 7 connectors, 5 ICs, 5 diodes and 2 crystals.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Arduino uno development board

A custom-designed printed circuit board (PCB) based on the Arduino Uno architecture, featuring full schematic capture, layout, and manufacturing-ready fabrication files.

This project contains the complete hardware design files for an Arduino Uno development board. It serves as a physical hardware platform for embedded C/C++ programming, prototyping, and peripheral integration.

Arduino-Uno: common questions

What microcontroller does the Arduino-Uno use?

The Arduino-Uno is built around the ATMEGA328-P, from the AVR/Arduino family.

How big is the Arduino-Uno PCB?

The Arduino-Uno measures 59.9 × 66.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Arduino-Uno?

46 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Arduino-Uno design files?

From the MohamedHassanExp/Arduino-Uno repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Arduino-Uno design in my own project?

Yes, under the terms of its MIT license, which MohamedHassanExp chose for the repository.

Can I test firmware for the Arduino-Uno without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
