NanoPi NEO Plus2 A Cool Tiny Raspberry Pi Challenger
The NanoPi NEO Plus2 is another Allwinner ARM board developed by FriendlyElec. It uses a 6-layers PCB layout featuring an Allwinner 64-bit quad-core A53 SoC with Hexa-core Mali 450 GPU and features 512MB – 1GB DDR3 RAM and 8GB EMMC. With a small form factor of only 40 x 52 mm the NanoPi NEO Plus2 has rich onboard resources that include: AP6212 WiFi & Bluetooth module, Gbps Ethernet and two USB hosts.
It supports the system to boot from both the Micro-SD card and the eMMC chip. There are few configuration possibilities for this board, you can use this board independently and assembled it in a compact semi-open Acrylic plastic case made from plastic or buy the metal type with better heat distribution. Similar to previous NanoPi NEO&NEO2 board series, based on the “older” generation 32-bit quad-core processor this board can also be used with the 1-bay NAS Kit to build a low-cost home NAS (Network-attached storage) server to backup data on a 2.5 inch hard drive, Having said that, you are welcome to check more information about the product features in the following links posted below:

Buying Advice and Prices
The board can be purchased at a starting price of 34$ for the 512MB RAM edition. The 1GB RAM is priced for a higher price of $42. Extra accessories including power supply and case are not included in the default package. Personally, I liked the metal case and I think its also worth the price. It can be used in high dirt industrial investments. As for the power adapter, it’s not a must-have item, if you have a tablet P.C 2A/3A power adapter with a micro USB plug it should be fine.
- NanoPi NEO Plus2 ($34 / $42)
- Metal Case Kit ($9.99)
- 5V 3A Universal USB Port Power Adapter (+$8.97) ($20)

- Download the DietPi Image
- Write the image to the SD card using Win32DiskImager / balenaEtcher Tool
- Boot the NanoPi NEO Plus2 from the card
- Finding the board IP address:
Method 1: Some advanced routers have LAN discover a feature that makes life easier viewing all connected devices across a local network.
Method 2: Use an IP network scanner
A network scanner is a useful tool for a network administrator. You can also use it to find your devices on your network. for this purpose, you can use Angry IP Scanner as it is simple and easy to use.
5. Download and install PuTTY software. Enter the IP address and run SSH
Flashing OS to 8GB eMMC Chip
Method #1: Flashing the image using dd
- After acquiring the DHCP / static IP address of the board.
- Install PuTTY software and select SSH protocol, enter your IP with port 22
- login with root / dietpi
- After runing fdisk -l to display storage devices, you would see the following line:
“/dev/mmcblk0p2 133120 15269887 15136768 7,2G 83 Linux”
/dev/mmcblk1 -> is your 8GB eMMC.
- Copy to the original image of DietPi to an NTFS formatted USB flash drive
- Create mount directory: mkdir /mnt/usb
- mount the USB flash drive running: mount /dev/sda1 /mnt/usb
- change path to /mnt/usb
- Execute the following command:
root@DietPi:/mnt/usb# dd if=dietPi.img of=/dev/mmcblk1 bs=512
- Wait few minutes until the process is over and run restart cmd
to boot the board.
- Now you are ready to configure Service, software, settings:
Method #2: Flashing the image with eflasher Utility
The simplest method to burn the image is burning the image on a microSD card using the Win32DiskImager / balenaEtcher Tool. After that step is finished, you just need to boot your device and the rest is done automatically.
NanoPi NEO Plus2
Powered with a quad-core 64bit H5 Allwinner SoC the NanoPi NEO Plus2 board provides decent performance, enough for running popular services like NAS, FTP and more. The H5 CPU frequency operates in the minimum frequency of 120 MHz up to Max frequency of 1248 MHz.
DietPi distribution is the most flexible and easy to use. to change CPU settings you can run ‘dietpi-config‘ that loads with GUI. under ‘Performance Options’ you can control and set Throttle ratio by specifying a nominal percentage value, choose a CPU Governor according to the type of usage. Also set minimum and maximum CPU clock frequency. Settings that directly impact operation including power consumption.

Compatibility with 1-bay NAS Dock Board
If you are planning on connecting a high capacity SSD / mechanical hard drive with the NEO Plus2, this combination would be a good pick, just keep in mind that if you decide to buy the 1-bay NAS Dock aluminium case it will not fit with the NanoPi NEO Plus2 because the board length is much longer, about 8-10mm in comparison to the NanoPi NEO/NEO2 board series.

Although the NEO Plus2 Board doesn’t have any video output interface and accessing it is done mainly through SSH connection, if you are asking what can you do with this board? the answer is simple. there are plenty of services you can run on it such as Print sharing service, NAS, VirtualHere, Samba, FTP, Pi-hole, Tor hotspot, WiFi hotspot and much more.
Metal Case Kit ($9.99)
A must-have accessory if you need a firm case to protect the board. The case kit also comes with a few extra items such as an external 4dB WiFi antenna, a thermal pad, and relatively large-high-quality heatsink to cool the H5 Chip.
The case main envelope is made from a rectangle-shaped profile, with two covers tightened with M2.5 screws on both sides. Because the case is completely closed, the only issue I had was gaining access to the header pins. Cutting a small window just above the pins could be a nice solution to this problem.

NEO Plus2 Heatsink
Included as part of the metal case kit. The heatsink is mounted against the H5 Chip using four M2.5×4.5mm screws and provided a terminal pad. From my checking, it would be wise buying additional two thermal pads with the same thickness as the H5 chip to also cool the eMMC and memory chips. Having said that, quality and design were both excellent and offer a great cooling solution for the board, as well as dirt protection.

NEO Plus2 | Putting it all together
Overall, I really liked the quality of the NanoPi NEO Plus2 board including all optional accessories. This small form factor board can best be used for many applications where you might have limited space to place a large size low consumption minicomputer. In my opinion, the retail price is too high and needs to be lower. Bottom line, if you have an extra $32-42 and seeking a small board I definitely recommend buying one with the metal case kit.
