Arduino mini: common questions

What microcontroller does the Arduino mini use?

The Arduino mini is built around the ATMEGA328P-A, from the AVR/Arduino family.

How big is the Arduino mini PCB?

The Arduino mini measures 21 × 21 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Arduino mini?

14 components, from 9 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 mini design files?

From the anxndsgn/Arduino-mini 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 mini design in my own project?

Yes, under the terms of its MIT license, which anxndsgn chose for the repository.

Can I test firmware for the Arduino mini 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.
