About the Arduino-Uno-R3-PCB-Design

Arduino-Uno-R3-PCB-Design is an open source AVR/Arduino PCB design by daviddzekwer, published on GitHub. It is a 2-layer board measuring 68.6 × 53.3 mm, with 60 components from 34 distinct parts.

Its main chip is the ATmega16U2-A, from the AVR/Arduino family. Other key parts include the LMV358, AP2112K-3.3, NCP1117-5.0_SOT223 and ATmega328P-P. By type, the board carries 18 resistors, 12 capacitors, 6 connectors, 5 ICs, 4 diodes and 2 crystals.

From the project

This project is a replica of the official Arduino Uno R3 designed using KiCad 10 as part of an Electrical and Electronics Engineering PCB Design assignment.

This project is a replica of the official Arduino Uno R3 designed using KiCad 10 as part of an Electrical and Electronics Engineering PCB Design assignment.

The project involved creating the complete Arduino Uno R3 schematic, assigning component footprints, designing the PCB layout, routing the board, performing electrical and design rule checks, and generating the manufacturing files required for PCB fabrication.

Arduino-Uno-R3-PCB-Design: common questions

What microcontroller does the Arduino-Uno-R3-PCB-Design use?

The Arduino-Uno-R3-PCB-Design is built around the ATmega16U2-A, from the AVR/Arduino family.

How big is the Arduino-Uno-R3-PCB-Design?

The Arduino-Uno-R3-PCB-Design measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino-Uno-R3-PCB-Design?

60 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Arduino-Uno-R3-PCB-Design design files?

From the daviddzekwer/Arduino-Uno-R3-PCB-Design repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Arduino-Uno-R3-PCB-Design design in my own project?

The repository has no license, so all rights stay with daviddzekwer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Arduino-Uno-R3-PCB-Design 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.
