What Are the Key Benefits of the ROCK 4 SE? 

Powerful Rockchip processor  

A low-power high-performing Rockchip RK3399-T processor is embedded into the heart of the ROCK 4 SE board. Equipped with an Arm® big.LITTLE™ technology Dual Cortex®-A72@1.5GHz, Quad Cortex-A53@1.0GHz CPU, Arm Mali™ – T860MP4 GPU and 4GB 64bit LPDDR4 RAM, be sure that your board will provide a high-performance solid as a ROCK!  

Extensive storage capacity 

ROCK 4 SE offers you an immense advantage over other competitors’ boards, benefiting from extensive storage capability. It features a Micro SD card, an eMMC and an M.2 (M key), ensuring the board with a tremendous amount of additional storage capacity.  

RTC (real-time clock)  

The onboard real-time clock allows you to accurately register the time even when the ROCK 4 SE is powered off. The board features an onboard connector for an RTC battery. 

Multiple connectivity capabilities 

The board offers you multiple connectivity capabilities, including Bluetooth 5.0, WiFi, Gigabit Ethernet, USB and HDMI ports, and a built-in antenna, allowing you to widely incorporate ROCK 4 SE into your applications.  

Highly compatible with SBC accessories 

ROCK 4 SE features an onboard 40P GPIO extension header, offering extensive compatibility with a wide range of SBC accessories. 

Advanced multimedia functions 

The ROCK 4 SE is fitted with an Arm Mali™ – T860MP4 quad-core graphics processing unit (GPU), ideal for advanced multimedia applications, including games. The board incorporates camera and display interfaces, an HDMI port supporting displays up to 4Kp60 resolution, a high-quality audio output via a 3.5mm onboard audio jack that supports microphone input as default, and much more. 

Why is ROCK 4 SE the perfect alternative to other popular SBCs? 

  • Better performance – 4GB 64bit RAM, more processing cores and a broader memory interface, 
  • Extensive storage capacity, 
  • Similar form factor, 
  • 40 pin GPIO extension header.

  • A viable, in-stock SBC, with some quirks.

    The little ROCK 4 SE is a board with a bit of heritage behind it. Radxa have been making different flavours of this board with a variety of processors and peripherals for several years. Also - it's in stock, which puts it way higher up the desirability level than the Pi or CM4, where you have to play hunt the board, sometimes for weeks to get one.

    Why only three stars then? Well, mostly because it's a bit inflexible in its current incarnation. The only option is the 4gb version. The Radxa ROCK 5 is already announced, with evaluation boards already in the wild and general availability expected in the next few weeks/months. It sports an extra 2 fast cores (bringing the total to 4 "big" cores and 4 "small" cores, and memory options of 4gb, 8gb or 16gb, plus 2.5gb Ethernet and a bunch of other upgrades. From that perspective then, you're buying a slightly older design, and a lower specification but that is available now and is cheaper than the ROCK 5 will be.

    There are some other quirks. Storage initially looks good - there are three options - SD card, eMMC or an M.2 NVME socket, however my initial excitement died a little when I realized that the M.2 socket is in a REALLY odd place on the board - it's on the bottom of the board, on one of the shorter edges, but it faces outwards which means that the NVME drive literally sticks out like a sore thumb, nearly doubling the length of the board.

    It couldn't have been mounted the other way because it would have sat directly above the processor. It's a bizarre, and not really viable solution. There is a fix though - an expansion card that mounts on top of the board and flips the socket over so the overhang on a 2280 card is much smaller, although it does still stick out a bit but it's not sold in the UK at the moment, so you'll have to buy from China or USA if you want usable NVME.

    On to the eMMC then, and again, eMMC is generally faster and more reliable than SD card, so a fair backup option in the absence of NVME. Except that the eMMC connector chip is specifically designed to fit specific 38pin/30pin high density connectors which aren't available in the UK, so again it's off to China or USA if you want to use eMMC. Plus eMMC is expensive, so not really great as a "one and only" drive. You do have some USB 3 ports too, so USB storage is an option, but I don't think the ROCK 4 can boot from USB drives (or I haven't worked out yet how to make it work).

    So then, that just leaves SD cards. I've had enough SD cards fail on me over the years that I wouldn't consider them as viable OS drives for anything but the most trivial of projects, but as of right now, that's really your only option to get started. I have been in contact with the OKDO technical team, and they acknowledged the storage shortcomings and are looking at options to address them, but they aren't available today.

    Summary: A useful little board, with more cores than a Raspberry Pi 4 but fixed at 4gb RAM, limited storage options at the moment, but in stock and not outrageously priced.
