About the Arduino-Nano-Project PCB

Arduino-Nano-Project is an open source AVR/Arduino PCB design by MaheshChowdaryDamuluri, published on GitHub under the MIT license. It is a 4-layer board measuring 40.8 × 18.2 mm, with 33 components from 18 distinct parts.

Its main chip is the ATmega328-M, from the AVR/Arduino family. Other key parts include the LM1117MP-5.0 and FT232RL. By type, the board carries 10 capacitors, 7 resistors, 5 connectors, 5 diodes, 3 ICs and 1 crystal.

It belongs with the usb & debug tools designs in this gallery.

From the project

Welcome to the official repository for the Custom Arduino Nano Hardware Clone project. This repository houses the full programmatic schematic blueprints, advanced multi-layer stackup routing configurations, and fabrication-ready source materials engineered entirely within the KiC

Welcome to the official repository for the Custom Arduino Nano Hardware Clone project. This repository houses the full programmatic schematic blueprints, advanced multi-layer stackup routing configurations, and fabrication-ready source materials engineered entirely within the KiCad design suite.

Unlike a standard commercial breakout board, this implementation optimizes power rail stability, enhances differential signal impedance, and introduces precise physical test points for desktop diagnostic verification.

Arduino-Nano-Project: common questions

What microcontroller does the Arduino-Nano-Project use?

The Arduino-Nano-Project is built around the ATmega328-M, from the AVR/Arduino family.

How big is the Arduino-Nano-Project PCB?

The Arduino-Nano-Project measures 40.8 × 18.2 mm, has 4 copper layers and is 1.326 mm thick.

How many components are on the Arduino-Nano-Project?

33 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Arduino-Nano-Project design files?

From the MaheshChowdaryDamuluri/Arduino-Nano-Project 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-Nano-Project design in my own project?

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

Can I test firmware for the Arduino-Nano-Project 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.
