The KiCad project lives in the ccadic/atmega328kb repository on GitHub; these links point at the commit this page was built from.

Atmega328kb: common questions

What microcontroller does the Atmega328kb use?

The Atmega328kb is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Atmega328kb PCB?

The Atmega328kb measures 112 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Atmega328kb?

74 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Atmega328kb design files?

From the ccadic/atmega328kb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Atmega328kb design in my own project?

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

Can I test firmware for the Atmega328kb 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.
