Arduino unoPB: common questions

What microcontroller does the Arduino unoPB use?

The Arduino unoPB is built around the ATMEGA328PB-AU, from the AVR/Arduino family.

How big is the Arduino unoPB PCB?

The Arduino unoPB measures 70.2 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino unoPB?

63 components, from 41 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 unoPB design files?

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

Can I use the Arduino unoPB design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Arduino unoPB 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.
