- NanoPi M4 Review, Specification, and Features.
The NanoPi M4 is a single board computer (SBC) based Rockchip RK3399 SoC designed by FriendlyElec company. It features the same form factor as well as ports and interfaces that are compatible with Raspberry Pi 3 Model B+ SBC. Measuring only 85 x 56 mm, making this compact board an ideal platform for rapid product prototyping, including a wide selection of industrial and commercial applications.
The NanoPi M4 has an onboard 2.4G & 5G dual-band WiFi and Bluetooth module, four USB3.0 TypeA host ports, one Gbps Ethernet port, one HDMI 2.0 Type-A port, one 3.5mm audio jack, one Type-C port. In addition, it has an RPi-compatible 40-pin connector which populates dual MIPI-CSI camera interface, PCIe x2, USB2.0, eMMC socket, RTC port and etc.
The NanoPi M4 comes in two editions with different RAM configurations. 4GB RAM LPDDR3 and 2GB RAM DDR2. Both boards can be booted from either a TF card or an external eMMC module (purchased separately). The NanoPi M4 supports Ubuntu Desktop 18.04 (64-bit), Lubuntu l6.04 (32-bit), Ubuntu Core 18.04 (64-bit), Android 7.1, and Lubuntu Desktop with GPU and VPU acceleration. With these rich resources and powerful performance, it can be used in a wide selection of applications, such as machine learning, AI, deep learning, robots, industrial control, industrial cameras, advertisement machines, game devices, blockchain and more depending on your imagination.

NanoPi M4 | All of the Items
All items, including extra accessories, came well-packaged and in excellent condition. The only small thing that was missing for me was the spec sheet paper usually added inside the board package, summarizing the hardware specs and explaining the board’s basic operation to a none geek person.

To make the M4 board cost-effective and flexible for the end user FriendlyElec incorporated an onboard eMMC socket that allows you to add a 16GB eMMC Module for a price of $12.00. it’s not a “must have” item, but if you want to gain quicker file read/ write speeds vs. loading all of them from a Micro SD Card it a definitely worth investing a few dollars.

Without digging into all the board details, if are planning on using this board as a type of Mini PC or a workstation, the hardware will provide above-decent performance suitable for running OpenOffice, Apps, surfing the web, and also watching 4K videos. The NanoPi M4 comes in two types of variants with different configurations, 2GB, and 4GB. The 2GB RAM will be enough for doing all and much more. Having said that, my best experience was running FriendlyDesktop 18.04 (64-bit) operating under light resources LXDE desktop environment worked much smoother compared to Lubuntu 16.04 (32-bit) and the general feeling was of no visible lags while moving windows across the screen or opening apps in the background.
One of the main highlights of this package and worth considering buying is the passive cooling Heatsink unit which costs $6.99. It’s composed of an aluminum block slightly larger than the PCB dimensions, and a set of 4 Philips-type screws along with a silicon thermal pad. Assembling the board is very simple. The back side of the board is placed above the heatsink, where the main RK33999 chip is located while applying pressure is against it.

Software Support & Benchmarks
If you are planning on using this board as a type of Mini PC or a workstation, the RK3399 hardware will provide the above-decent performance suitable for running OpenOffice, Apps, surfing the web, and also watching 4K videos. The NanoPi M4 comes in two types of variants with different configurations, 2GB, and 4GB. The 2GB RAM will be enough for doing all and much more, but if you need extra RAM the 4GB edition will cost you an additional $30. Having said that, my best experience was running FriendlyDesktop 18.04 (64-bit) operating under light resources LXDE desktop environment worked much smoother compared to Lubuntu 16.04 (32-bit) and the general feeling was of no visible lags while moving windows across the screen or opening apps in the background.
Based on the following benchmark test results performed under FriendlyDesktop 18.04 environment, the Hardware performance was pretty good for a $65 SBC (Single Board Computer) with processing power that is slightly lower than a low-end Desktop PC.
