The Nano V3 is a compact ATmega328PB-AU development board with a modern USB-C port and the FT232 USB-to-serial chip for reliable, driver-friendly connectivity. Fully compatible with the Arduino IDE, it's a breadboard-friendly board for prototyping, learning and embedded builds. Headers come pre-soldered — plug straight into a breadboard, no soldering required.

Great for
Getting started
- Install the Arduino IDE
Download from arduino.cc if you don't have it yet. Any recent version works.
- Install the FT232 driver if needed
Windows and macOS usually detect the FT232 automatically. If no COM port appears, download the driver from ftdichip.com.
- Select the board and processor
Tools → Board → Arduino Nano. Set Processor to ATmega328P. If upload fails at the end, try ATmega328P (Old Bootloader).
- Upload your sketch
Select the correct COM port and hit Upload. The board can also be programmed via ISP if needed.
Common questions
Is this a genuine Arduino board?
No — it's an Arduino-compatible Nano that works with the free Arduino IDE exactly like an official board. It uses the ATmega328PB-AU microcontroller and FT232 USB-to-serial chip rather than the official Arduino's SAMD or ATmega16U2.
What's the difference between FT232 and CH340?
The FT232 is a higher-quality USB-to-serial chip from FTDI that is natively supported on Windows, macOS and Linux without needing a driver install in most cases. The CH340 is a cheaper alternative that often requires a manual driver install. This board uses the FT232 for more reliable connectivity.
Which board and processor do I select in the IDE?
Select Arduino Nano with ATmega328P processor. If the upload fails at the very end of the process, switch the processor to ATmega328P (Old Bootloader) — this fixes the issue on most compatible boards.
Are the headers already soldered?
Yes — this is the pre-soldered version. Header pins are already attached and the board is ready to plug straight into a breadboard. We also stock an unsoldered Nano if you prefer to fit your own headers.
What power sources does it support?
The board can be powered via USB-C, an external 3.3V–12V DC supply, a lithium battery, a 9V battery, or via ISP. The power source is automatically selected.
Is it 5V or 3.3V logic?
5V logic, the same as an Arduino Uno — most 5V shields, modules and sensors work directly without level shifting.
Good to know: This board uses the ATmega328PB-AU and FT232 — a step up from the common CH340G + ATmega328P combination. Every board is checked before it ships from our Te Awamutu stock. If you'd prefer unsoldered headers, we stock that variant too.
