The Nano V3.0 is a compact ATmega328P development board with a modern USB-C port and the CH340G USB-to-serial chip. Fully compatible with the Arduino IDE, it's a breadboard-friendly board for prototyping, learning and embedded builds. Headers come unsoldered, with loose strips to fit yourself, ideal for low-profile or custom wiring.

Specifications
What's in the box
Headers are supplied unsoldered so you can solder your own or wire directly for custom builds.
Great for
Getting started
- Fit your headers
Solder the included header strips, or wire directly to the pads for a low-profile build.
- Install the CH340 driver if needed
Most systems detect the CH340G automatically. If no COM port shows, install the CH340 driver.
- Select the board
Tools → Board → Arduino Nano, and set Processor to ATmega328P.
- Upload
Pick the COM port and upload. If it fails at the end, switch the processor to "ATmega328P (Old Bootloader)".
Common questions
Are the headers soldered on?
No. This is the unsoldered version. It includes loose header strips so you can solder your own or wire directly, handy for low-profile or permanent builds. If you'd rather plug straight in, we stock a pre-soldered Nano V3.
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 common CH340G USB chip.
Do I need to install a driver?
The board uses the CH340G USB-to-serial chip. Most systems detect it automatically, but some may need the CH340 driver installed.
Which board and processor do I select?
Choose Arduino Nano with the ATmega328P processor. If the upload fails right at the end, switch the processor to "ATmega328P (Old Bootloader)".
Is it 5V or 3.3V logic?
5V logic, the same as an Arduino Uno, so most 5V shields, modules and sensors work directly.
Good to know: This is a 5V logic board and headers are supplied unsoldered. Every board is checked before it ships from our Te Awamutu stock.
