Introduction
The NanoPi NEO Plus2 is another Allwinner based
ARM board developed by FriendlyElec. It uses
Allwinner's 64-bit quad-core A53 SoC with hexa-
core Mali450 GPU and features 1GB of DDR3 RAM
and 8GB eMMC.
With a small size of only 40 x 52mm the NanoPi
NEO Plus2 has rich on-board resources: AP6212A
WiFi & Bluetooth module, Gbps Ethernet and two
USB hosts. It supports system-boot from a MicroSD
card.
The NanoPi NEO Plus2 has a carefully designed
power system and 6-layer PCB layout. These
features enhance the board's heat dissipation.
The NanoPi NEO Plus2 meets popular IOT
applications requirements for small size, high-speed
and large throughput data transmission and high
performance computing.

Get Started
Essentials You Need
Before starting to use your NanoPi NEO Plus2 get the following items ready:
5/13

NanoPi NEO Plus2
microSD Card/TFCard: Class 10 or Above, minimum 8GB SDHC
microUSB power. A 5V/2A power is a must
A Host computer running Ubuntu 14.04 64 bit system
TF Cards We Tested
To make your NanoPi NEO Plus2 boot and run fast we highly recommend you use a Class10 8GB SDHC TF
card or a better one. The following cards are what we used in all our test cases presented here:
SanDisk TF 8G Class10 Micro/SD TF card:
SanDisk TF128G MicroSDXC TF 128G Class10 48MB/S:
川宇 8G C10 High Speed class10 micro SD card:

Make Installation MicroSD Card
Extract the nanopi-neo-plus2_ubuntu-core-xenial_4.x.y_YYYYMMDD.img.zip and win32diskimager.rar.
Insert a MicroSD card(at least 8G) into a Windows PC and run the win32diskimager utility as
administrator. On the utility's main window select your card's drive, the wanted image file and click on
"write" to start flashing the card till it is done.
Insert this card into your NEO Plus2's MicroSD card slot and power on (with a 5V/2A power source). If the
blue LED blinks this indicates your NEO Plus2 has successfully booted.
Flash Image to eMMC
Extract the nanopi-neo-plus2_eflasher_4.x.y_YYYYMMDD.img.zip package and win32diskimager.rar.
6/13

Insert a MicroSD card(at least 8G) into a Windows PC and run the win32diskimager utility as
administrator. On the utility's main window select your SD card's drive, the wanted image file and click on
"write" to start flashing the MicroSD card.
Insert this card into your NEO Plus2 and power on (with a 5V/2A power source) the board. If the green
LED is on and blue LED is blinks it indicates your eflasher has started successfully.
Run the following command on a terminal:
$
eflasher
Select your wanted OS and type "yes" to start flashing. After it is done take off the card, reboot your board it will
boot from eMMC.
Work with Ubuntu-Core with Qt-Embedded
Run Ubuntu-Core with Qt-Embedded
If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM
board, which will allow you to operate the board via a serial terminal.Here is a setup where we connect a
NanoPi NEO Plus2 to a PC via the PSU-ONECOM and you can power on your NEO Plus2 from either the
PSU-ONECOM or its MicroUSB:
You can use a USB to Serial conversion board too. Make sure you use a 5V/2A power to power your NEO Plus2
from its MicroUSB port:

By default pi logs in automatically. You can disable its auto-login by using "sudo npi-config".
Update Software Packages:
sudo apt-get
update
Configure System with npi-config
The npi-config is a commandline utility which can be used to initialize system configurations such as user
password, system language, time zone, Hostname, SSH switch , Auto login and etc. Type the following
command to run this utility.
$ sudo npi-
config
Here is how npi-config's GUI looks like:

Ethernet Connection
If the NanoPi NEO Plus2 is connected to a network via Ethernet before it is powered on it will automatically
obtain an IP after it is powered up. If it is not connected via Ethernet or its DHCP is not activated obtaining an IP
will fail and system will hang on for about 15 to 60 seconds. Obtain an IP address
dhclient
eth0
Login via SSH
The NanoPi NEO Plus2 doesn't have a video output interface. You can log into the board via SSH. In our test the
IP address detected by our router was 192.168.1.230 and we ran the following command to log into the NanoPi
NEO Plus2:
$ ssh
root@192.168.1.230
The password is fa
Extend NEO Plus2's TF Card Section
When Ubuntu is loaded the TF card's section will be automatically extended.You can check the section's size by
running the following command:
$ df -
h
Wireless Connection
Note: An IPX antenna is A MUST.
After your NanoPi NEO Plus2 is powered up you can log into NEO Plus2 and run the following command to
check if a WiFi device is recognized. If "wlan0" is listed it indicates your WiFi has been recognized:
sudo ifconfig -a
9/13

Open the file "/etc/wpa_supplicant/wpa_supplicant.conf" with vi or gedit and append the following lines:
network={
ssid="YourWiFiESSID"
psk="YourWiFiPassword"
}
The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.
Save, exit and run the following commands your board will be connected to your specified WiFi:
ifdown wlan0
ifup wlan0
If your WiFi password has special characters or you don't want your password saved as plain text you can use
"wpa_passphrase" to generate a psk for your WiFi password. Here is how you can do it:
wpa_passphrase
YourWiFiESSID
Following the prompt type in your password. If you open the file "/etc/wpa_supplicant/wpa_supplicant.conf" you
will find that your password has been updated and you can delete your clear-text password.
Connect NanoPi NEO Plus2 to USB Camera(FA-CAM202)
The FA-CAM202 is a 2M-pixel USB camera module. Boot your NEO Plus2, connect it to the internet, log in the
system as root, compile and run the mjpg-streamer utility:
