Arduino: common questions

What microcontroller does the Arduino use?

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

How big is the Arduino PCB?

The Arduino measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino?

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

Where can I download the Arduino design files?

From the cristobalcuevas/PCB-Designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Arduino design in my own project?

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

Can I test firmware for the Arduino 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.
