Arduino: common questions
What microcontroller does the Arduino use?
The Arduino is built around the ATmega2560-16A, from the AVR/Arduino family.
How big is the Arduino PCB?
The Arduino measures 43.3 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Arduino?
41 components, from 21 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 design files?
From the odobot/PCB_DESIGN repository on GitHub, which has the KiCad layout, the schematic and the BOM; 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 odobot. 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.
