Build Faster with the Nano V3.1 by DFRobot Arduino Compatible
Nano V3.1 by DFRobot Arduino Compatible - The Nano V3.1 by DFRobot Arduino Compatible is a breadboard-ready version of the Arduino mini with integrated USB. The Nano has everything that the Diecimila has (electronically) with more analog input pins and an onboard +5V AREF jumper. The Nano automatically senses and switches to the higher power supply, so there is no need for a power select jumper.
The nano's pin layout works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other). The Arduino Nano V3.1 DFRobot USB Microcontroller V3.1 (ATMega 328) can be powered via the mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected as the highest voltage source.
Important: Use the official DFRobot links below for wiring, sample code, downloads, and the latest setup notes for this SKU.
Why you'll love it
- v3.0 - improved the analog port pin mapping to be compatible with the original Arduino Nano
- v3.1 - changed the Mini USB port to a Micro USB port
- Automatic reset during program download
- Power OK blue LED on the bottom
- Green (TX), red (RX), and orange (L) LED
- +5V to AREF jumper

Pinout & usage notes
Use the correct SDA and SCL pins on your controller and make sure the bus voltage is compatible. Verify serial levels, baud rate, and pin mapping in the official DFRobot guide before first power-up. For analog readings, use a stable reference and keep wiring short when possible for cleaner signals.

Frequently Asked Questions
Is this a good choice for learning and prototyping? Yes. It is well suited for classroom work, hobby builds, quick tests, and project development with common modules and sensors.
Does it work with other boards too? Often yes, as long as voltage, interface, and pin mapping match. ESP32 and Raspberry Pi users should still check the official docs first.
Where can I find wiring and examples? Use the official DFRobot product page and wiki links below for guides, downloads, and code examples.
