ATmega328PB-usb bread board: common questions

What microcontroller does the ATmega328PB-usb bread board use?

The ATmega328PB-usb bread board is built around the ATmega328PB-MU, from the AVR/Arduino family.

How big is the ATmega328PB-usb bread board?

The ATmega328PB-usb bread board measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATmega328PB-usb bread board?

29 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the ATmega328PB-usb bread board design files?

From the asukiaaa/ATmega328PB-usb-bread-board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ATmega328PB-usb bread board design in my own project?

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

Can I test firmware for the ATmega328PB-usb bread 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.
