Nanopi R4S Review, Specs, Features and Highlights

Nanopi R4S

FriendlyElec expected to launch a new Nanopi R4S SBC. This is a small complete computer on a circuit board. The SBC is based on the Rockhip RK3399 , powered with six ARM cores CPU with a combination of Cortex-A72 dual-core and Cortex-A53 quad-core next to a Mali-T864 graphics unit.

The Nanopi R4S is a headless system without a display interface. But it can be used as a printer server, network router, file server or for various purposes that do not require a screen.


Hardware

Compared to its predecessor NanoPi R2s FriendlyElec offers 1 GByte or 4 GByte DDR3 RAM configurations on at small PCB measuring 66 x 66 mm, so the board is very compact and can be placed almost in every environment without occupying too much space. There is no eMMC flash on-board, but a micro SD card socket/slot comes built-in on the board capable of loading Linux systems on the memory card. There are also two USB 3.2 Gen 1 sockets, an onboard USB 2.0 header and a micro USB connection for the power supply. Two Gigabit Ethernet sockets (RJ45) make the mini-computer interesting for network application along with an external 10-pin GPIO interface.

Software

As most FriendlyElec SBCs, likely, the new expect Nanopi R4S board will mainly support Ubuntu/ OpenWRT Software so you would also be able to use it as a mini portable travel router to maximize your cybersecurity protection. So stay tuned, when we get our hands on the sample, we will post a full detailed hands-on review.
