FriendlyARM NanoPC T3
The NanoPC-T3 is a single-board computer designed and developed by FriendlyARM Company. It uses the Samsung Octa-Core Cortex-A53 S5P6818 SoC. Compared to the NanoPC-T2 the NanoPC-T3 is equipped with additional interfaces and ports, along with a more powerful SoC. Its dynamic frequency scales from 400MHz up to 1.4GHz. The NanoPC-T3 has an 8G eMMC on-board flash, audio jack, video input/output interfaces, built-in WiFi, Bluetooth, and a Gbps Ethernet port. In addition, the NanoPC-T3 has a power management chip, onboard porcelain antenna, and serial debug port.
Other features include two camera interfaces: a DVP camera interface and a MIPI-CSI interface, and four video interfaces: HDMI 1.4A, LVDS, parallel RGB-LCD interface, and MIPI-DSI interface. It has RTC interface pins, two USB 2.0 Host ports, and an additional two onboard via an external interface using an 8 or 9-pin header pin cable.

The NanoPC-T3 board is currently sold for a retail price of $60. If you need extra accessories, such as a case or WiFi Antenna it will cost you an additional few extra bucks. If you’re planning in buying a Heatsink this board comes with two mounting holes that provide tight surface contact for efficient heat conductivity, so I personally recommend buying it.
Jumping into the housing design. The NanoPC-T3 case is composed of two separate parts made of transparent acrylic material, with built-in metal inserts for mounting the board and the upper case cover. to make the product more user-friendly, the company added printed on box labels with the interface descriptions.
Now, for the problems. The case design, in general, was good, but I didn’t understand why additional venting slots where not added above the Heatsink to get the heat out more quickly, opposed to the lower case part that did have venting slots. In addition, on the upper cover didn’t have any slots/holes for the GPIO header, on-board USB Host, LVDS, LCD RGB-LCD, camera DVP, and MIPI-DSI cables. The power, reset and u-boot button was positioned in such way that the user needs to remove the upper cover of the case in order to gain access to use them, where the correct design is designing housing that allows the user to operate all functions externally, without opening or removing any cover.
FirendlyARM offers an aluminum-made passive Heatsink with a pair of mounts that attaches to two holes in the PCB and provide decent cooling, but it’s highly recommended adding a 30 mm fan on top of it. The problem was with the case height, that was not enough for adding a fan and closing the case upper cover, so again, you will need to keep the case open without the upper cover. Alternatively, you can also replace the Heatsink or just build a better case.

FirendlyArm NanoPC T3 Board Layout
NanoPC-T 3 | Full Board View
The hardware platform is based on the same S5P6818 Octa-Core Cortex-A53 Samsung 64-bit processor operating at clock frequency between 400 MHz Up to 1.4 GHz equipped with a Mali 400MP GPU which is also used in the previous NanoPi M3 board. for most computing tasks such as internet surfing, running office suite, streaming video this board provides a smooth and good experience, Just don’t expect the hardware to run heavy games.
A few significant changes in this model are the additional 8GB eMMC flash, Manual power switch, boot selection button, on-board Power switch, RTC Battery connector, and the microphone. Just as with the M3 model, FriendlyArm also included on-board external USB Host interface to be used with an 8 or 9 pins header cable which provides two additional ports by using a special 9 pin cable or PCB type USB Host adapter (Shown in the photo below).
Because FriendlyARM uses a relative less popular SoC for single board computer applications, made by Samsung so image selection is pretty limiting, and include three types: Android lollipop, Debian Jessie and Ubuntu Core. After playing with Debian Jessie and Android Images, the general impression is that the system worked well and stable.

Performance & Benchmarks
The Nano PI T3 is based on the 64-bit Samsung S5P6818 Octa-Core Cortex-A53 SoC that provides an excellent performance power consumption ratio. According to system information under Debian OS (32-Bit), each core operates at frequencies ranging from 400MHz up to 1.4 GHz.

Operation: Burning Images
The process of loading images from the Micro SD card is very simple. you have two main tools ‘SDFormatter’ and ‘Win32Disk Imager’ for formatting the media card and writing images. If you want to write the images to the 8GB eMMC you will need to use the ‘eflasher’ Tool which is similar to the raspberry pi NOOBS operating system installer, that does it almost automatically through a GUI. There you select the preferred OS and the installation wizard does the rest of the job, without any special howto technical knowledge or skills on the user side.

Network Throughput Test
In this test, one system must act as a server, while the other acts as a client. In this case, I ran iperf-3.1.3 (win64) as a server on a Windows 7 workstation and the NanoPi T3 was the client.
Step 1 – Finding out the Windows workstation & NanoPi T3 IP Address
- CMD For Windows: ipconfig
- CMD For Linux: # ifconfig
Step 2 – Running ssh service on the NanoPi T3
sudo service ssh start
Step 3 – Installing PUTTY ssh client and connecting to the NanoPi T3
Step 4 – Downloading the latest ipref3 ( Windows OS ) :
Download Link: https://iperf.fr/iperf-download.php
Step 5 – Setting the Windows Workstation in Server mode (port: 45678)
From Windows Command line running: iperf3 -s -p 45678
Step 7 – Installing ipref3 package on the NanoPi T3
sudo apt-get install iperf
Step 8 – Running Tests from the NanoPi T3 on target IP (Windows Station):

In terms of hardware, the NanoPC-T3 is defiantly a good high-performance board, that can be used also as a workstation / Mini PC to run Android and Debian Linux. As for software support, the user is limited only to three types of OS. FriendlyARM could have done a better job and provide more OS images.
Pros / Cons:
- High performance (Octa-Core Processor)
- A wide selection of onboard interfaces
- 1GB RAM
- Limited software support (Linux, Ubuntu Core, Android).
