ATMega328P: common questions

What microcontroller does the ATMega328P use?

The ATMega328P is built around the ATmega8-16A, from the AVR/Arduino family.

How big is the ATMega328P PCB?

The ATMega328P measures 58.9 × 52.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATMega328P?

26 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the ATMega328P design files?

From the PrashilLamichhane/ATMega328P repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ATMega328P design in my own project?

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

Can I test firmware for the ATMega328P 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.
