Arduino-UNO-Clone: common questions

What microcontroller does the Arduino-UNO-Clone use?

The Arduino-UNO-Clone is built around the ATMEGA328-M, from the AVR/Arduino family.

How big is the Arduino-UNO-Clone PCB?

The Arduino-UNO-Clone measures 68.6 × 53.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino-UNO-Clone?

51 components, from 34 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-UNO-Clone design files?

From the swapnil-maurya/Arduino-UNO-Clone-PCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Arduino-UNO-Clone design in my own project?

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

Can I test firmware for the Arduino-UNO-Clone 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.
