About the Custom-Arduiono-Board

Custom-Arduiono-Board is an open source AVR/Arduino PCB design by marrynrv, published on GitHub. It is a 2-layer board measuring 68.6 × 53.3 mm, with 57 components from 29 distinct parts.

Its main chip is the ATMEGA328PB-A, from the AVR/Arduino family. Other key parts include the LMV358, LP2985-3.3, NCP1117-5.0_SOT223 and ATMEGA16U2-A. By type, the board carries 15 capacitors, 14 resistors, 8 connectors, 6 diodes, 5 ICs and 2 crystals.

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

From the project

Custom Arduino-compatible microcontroller development board designed in KiCad based on the classic Uno reference schematic

A custom-designed development board built from scratch in KiCad EDA, based on the ATmega328PB microcontroller architecture and the classic Arduino Uno reference design.

This project was created as a practical hands-on hardware engineering task to master schematic capture, SMD component placement, USB-to-UART interface integration, power regulation, and manufacturing output preparation.

Custom-Arduiono-Board: common questions

What microcontroller does the Custom-Arduiono-Board use?

The Custom-Arduiono-Board is built around the ATMEGA328PB-A, from the AVR/Arduino family.

How big is the Custom-Arduiono-Board?

The Custom-Arduiono-Board measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom-Arduiono-Board?

57 components, from 29 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 Custom-Arduiono-Board design files?

From the marrynrv/Custom-Arduiono-Board 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 Custom-Arduiono-Board design in my own project?

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

Can I test firmware for the Custom-Arduiono-Board 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.
