Perfect for lightweight IoT projects

This board is incredibly small yet powerful enough for my home automation sensors. The GPIO access is straightforward, and the community support for Armbian is excellent.

Reliable for industrial prototyping

We use these in our lab for rapid prototyping of control systems. They have been running 24/7 for months without any issues. Very stable.

Great value but needs a good heatsink

For the price, you can't beat the performance. However, the CPU does get warm under load, so I highly recommend adding a small heatsink if you plan to run it continuously.

Good board, steep learning curve for beginners

The hardware is solid, but if you are new to command-line interfaces, be prepared to do some reading. Once set up, it works flawlessly.

Tiny powerhouse

Used this as the brain for a small rover. The size allowed me to fit it into a tight chassis, and the Ethernet connection provided stable control latency.

Excellent learning tool for Linux

I bought this to teach my students about embedded Linux. The documentation is clear, and booting from an SD card is seamless. Highly recommended for education.

5 FAQ

Q: Does this board come with a power adapter included?

A: No, the package typically includes only the board. You will need to provide your own 5V/2A MicroUSB power supply.

Q: Does the GPIO header support 5V logic levels?

A: Most GPIO pins operate at 3.3V logic levels. Applying 5V directly to these pins may damage the board. Please use a level shifter if interfacing with 5V devices.

Q: What is the difference between the NEO and NEO2 models?

A: The primary difference is the processor and network speed. The NEO uses the H3 chip with 10/100M Ethernet, while the NEO2 uses the H5 chip with Gigabit Ethernet and slightly better CPU performance.

Q: Can I run Windows 10 on the NanoPi NEO?

A: No, the Allwinner H3/H5 architecture does not support standard Windows 10. It is designed for Linux-based distributions like Debian, Ubuntu, or Android.

Q: Is there a case available for this specific board size?

A: Yes, there are several third-party acrylic and 3D-printable cases available that fit the 40x40mm form factor. Please check our accessories section for compatible options.
