Nano original: common questions
What microcontroller does the Nano original use?
The Nano original is built around the ATmega328P-MUR, from the AVR/Arduino family.
How big is the Nano original PCB?
The Nano original measures 43.2 × 18 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Nano original?
26 components, from 20 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 Nano original design files?
From the feastorg/nano-dev-boards 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 Nano original design in my own project?
Yes, under the terms of its GPL-3.0 license, which feastorg chose for the repository.
Can I test firmware for the Nano original 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.
