Solid performance, minor pin labeling issue
The board functions exactly as expected for my sensor projects. The only downside is that the silk screen printing for the pins is slightly faint, but readable with good light.

Reliable clone
I have used many different versions of the NANO, and this V3.0 with the improved CH340G is very stable. No connection drops during code uploads.

Great for university projects
Bought five of these for a robotics class. All of them worked out of the box. The compact size fits perfectly into our custom 3D printed chassis.

Perfect for beginners and prototyping
This NANO board works flawlessly with the Arduino IDE. The CH340G driver was easy to install on Windows 10. Great value for the price compared to official boards.

Compact and powerful
Love the small form factor. It has all the power of the Uno but takes up half the space on my breadboard. Highly recommended for embedded learning.

Good value but needs driver setup
Excellent hardware for the money. Just remember you need to download the CH340 drivers separately if you are on an older OS. Once set up, it runs great.
Q: Can I power this board with a 9V battery?
A: Yes, you can power the board via the VIN pin using a 9V battery. The onboard regulator will step it down to the required 5V for the microcontroller.
Q: Is this compatible with Mac OS Catalina?
A: Yes, it is compatible. However, you may need to install the specific CH340G drivers available from the manufacturer's website to ensure recognition by the system.
Q: Does this board come with headers pre-soldered?
A: No, this board typically comes without headers soldered to allow for flexible mounting options. You will need to solder them yourself or use female header strips.
Q: Does this support the standard Arduino libraries?
A: Absolutely. Since it uses the ATmega328P chip, it is fully compatible with the vast majority of standard Arduino libraries and examples found in the IDE.
Q: What is the maximum current this board can supply via the 5V pin?
A: The 5V pin is directly connected to the USB power source. It is generally safe to draw up to 500mA, depending on your computer's USB port limits, but we recommend staying under 400mA for stability.
