Arduino Nano: common questions
What microcontroller does the Arduino Nano use?
The Arduino Nano is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.
How big is the Arduino Nano PCB?
The Arduino Nano measures 43.2 × 17.8 mm, has 4 copper layers and is 1.600198 mm thick.
How many components are on the Arduino Nano?
33 components, from 25 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 Nano design files?
From the SREE-VISHNU-N/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 Nano design in my own project?
The repository has no license, so all rights stay with SREE-VISHNU-N. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Arduino Nano without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
