About the Project3 4layer PCB

Project3 4layer is an open source AVR/Arduino PCB design by AronAyub, published on GitHub. It is a 4-layer board measuring 57.1 × 33.9 mm, with 17 components from 16 distinct parts.

Its main chip is the ATmega328P-PU, from the AVR/Arduino family. Other key parts include the DS1337_PDv2 and 24LC1025. By type, the board carries 4 ICs, 4 connectors, 3 capacitors, 2 crystals, 2 resistors and 1 battery holder.

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

kicad design projects

In this repository I have provided my previous KICAD PCB Designs for: ### Arduino hat - this is a complete arduino hat, check the folder for files! it is among my first designs

- this is a simple power supply unit which accepts 12V, 1A and gives, 3V3 and 5V as output, it is among my first designs

- mini Pi Hat, one of my old PCB design projects !

Project3 4layer: common questions

What microcontroller does the Project3 4layer use?

The Project3 4layer is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Project3 4layer PCB?

The Project3 4layer measures 57.1 × 33.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Project3 4layer?

17 components, from 16 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 Project3 4layer design files?

From the AronAyub/KICAD repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Project3 4layer design in my own project?

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

Can I test firmware for the Project3 4layer 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.
