ODROID-XU4 Development Board Price Drops to $59, Now Supports Linux 4.9 LTS

ODROID-XU4 development board powered by Samsung Exynos 5422 octa-core processor launched in summer 2015, but even after two years, it’s one of the fastest, if not the fastest, low cost development board on the market. It is also equipped with Gigabit Ethernet and USB 3.0 ports, but so far at $74, it was quite much expensive than slower peers. Hardkernel has now decided to lower the price to $59 plus shipping, which is really a good deal in terms of price/performance, and you’ll also benefit from close to two years development, as the board now supports Linux 4.9 with updates promised until early 2019.

Here’s a reminder of the technical specifications:

  • SoC – Samsung Exynos 5422 quad core ARM Cortex-A15 @ 2.0GHz + quad core ARM Cortex-A7 @ 1.4GHz with Mali-T628 MP6 GPU supporting OpenGL ES 3.0 / 2.0 / 1.1 and OpenCL 1.1 Full profile
  • System Memory – 2GB LPDDR3 RAM PoP (750 MHz, 12GB/s memory bandwidth, 2x32bit bus)
  • Storage – Micro SD slot (up to 64GB) + eMMC 5.0 module socket (16, 32, and 64GB modules available)
  • Video Output – HDMI 1.4a port up to 1080p
  • Audio Output – HDMI, optional S/PDIF out via USB module
  • Network Connectivity – Gigabit Ethernet, and optional USB Wi-Fi dongle with antenna
  • USB – 2x USB 3.0 host port, 1x USB 2.0 ports
  • Expansion – 30-pin header for access to GPIO, IRQ, SPI and ADC signals + 12-pin headers for GPIOs, I2S, and I2C
  • Debugging – Serial console header
  • Misc – Power and RGB LEDs, cooling fan header, power button, RTC
  • Power Supply – 5V/4A power adapter (recommended) using 5.5/2.1mm barrel.
  • Dimensions – 82 x 58 x 22 mm
  • Weight – 60 grams with fan; 38 grams without cooler

One reason why the price is cheaper, is that the 5V/4A power adapter is not included by default, and if you don’t have your own, it will add $5.50.You’ll also find a list of accessories such as eMMC modules, enclosure, Cloudshell NAS kit, expansion boards, displays, etc… on the product page linked in the introduction.

The board can run various official or community-developed operating systems such as Ubuntu 16.04 + OpenGL ES + OpenCL, Android 4.4 to Android 7.0, Debian Jessie, Kali Linux 2.0, Arch Linux ARM, etc… and it is also supported by the Yocto Project. You’ll find the images and documentation on the Wiki, the source code is available on Github, and support in the active odroid forums and/or #odroid IRC channel.

Unlike what you expect from Chinese sellers, shipping is about $19 btw, meticulously included on the customs declaration. (so forget about under-€23 customs + VAT waiver in Europe)

With no BT, no Wi-Fi and that soon-to-be-released ASUS board mentioned in the story below, they must be getting desperate to sucker a few more people.

Asus Tinker board is withdrawn from sale. You can’t find it anymore in CPC.
As CPC said, they removed it because there were software issues.
If it was just software issues, I don’t think that they withdrawn it from the market, something else is going on.

GanjaBear,

I am fairly certain the XU4 will handily beat an Asus tinker board – twice the number of cores and USB3.

I’ve been trying to get my hands on a Tinkerboard (CPC, Asus, and other distributors) but it is not available in North America yet, so I can give it a spin.

Meanwhile, those curious, can see my (rather long) XU4 vs Pi vs many others at

USB 3.0 and Gbit Ethernet are still key competitive features even the xu4 was introduced in 2015.
Upstream Kernel 4.9 support is also very impressive.
Antutu score on Android 7.1 is near 62K.

$59 seems to be really worth for me. I hope EU distributors will lower their price soon.


Do you have any plan to review their new Linux Kernel on Ubuntu as well as Lineage Android 7.1?

That would have been my dream board a few years ago — a quad A15 with 128-bit-wide SIMD at top-for-the-uarch clocks, properly cooled, a beefy Midgard GPU with OCL, and 2GB of high-BW RAM, all in ubunty, all at a proper price – nothing more I could wish for. Alas, I’ve since migrated most of my interesting projects to ARMv8 and I have mainly old stuff left for ARMv7. .. I’m still tempted to get ODROID-XU4 just on principle, to see “what it could have been” ; )

okay checking the xu4 block diagram, there are a couple of things to notice, if you worry about IO performance (NAS and such) : – Gigabit is achieved using one of the two USB 3.0 hosts of the Exynos 5422 with a GBe controller (haven’t looked which one), so Gbe performance would need to be tested. – Then the 2 USB 3.0 ports use a hub connected to the second USB 3.0 host on the chip, so they will share bandwidth. If the 5422 performs well on its usb 3.0 bus then it’s not really a problem (5Gbit/2 > 480Mbit)… Read more »

Yes, I use quite a bit of intrinsics in my code, and ASIMD2 (NEON2) generally has much better compiler support than the original NEON, due to the new simd register file model in ARMv8.

@tkaiser Well, if nothing else this board will likely remain the ARMv7 performance leader forever – top A15 clock, 2MB of L2 on the big cluster, and 12GB/s worth of LPDDR3. As much as I like RK3288, RK tend to under-perform in the RAM department, and their 1MB of L2 will not help in a comparison. The GPU comparison remains undecided, though – T760 MP4 vs T628 MP6 at the same clock. But GPUs “breath” BW, so that might give the Exynos the edge again. I’ll get some of my old GLES code (and if time permits – my newer… Read more »

@blu Well, GPU is not relevant for my use cases, it’s CPU power and network and IO bandwidth. While all of this relies on USB3 results look pretty good. In fact ODROID XU4 is the only beefy SBC out there with reasonable IO bandwidth (all the other octa-core boards I have — Banana Pi M3 and NanoPi M3 — totally suck here with just one single USB2 connection used, same applies to the two RK3288 designs — MiQi board and ASUS Tinker Board — too) And another thing to add: Hardkernel engineers responsibly designed power circuitry, they use a sane… Read more »

Small addendum regarding CPU horsepower comparing XU4 with MiQi (will be the same with Tinker Board): https://forum.armbian.com/index.php/topic/2045-armbian-on-miqi-sbc-hardware/?p=26427

For a fair comparison RK3288 should also run with latest mainline kernel though (and adding Willy Tarreau’s ‘performance patches’ of course). Hmm… I’ll wait two more weeks and when XU4 price drops and pollin.de also has Tinkerboard in stock I’ll order both and compare.

@tkaiser how would the XU4 do as a NAS with RAID? given that ethernet is on one usb3 controller, you would want to maximize thp to get >100MB/s — so maybe use just 1 usb3 port and don’t use the second for anything? using 1 HDD shouldn’t be an issue then – with kernel 4.9 it was reported to do >200MB/s which is more than the eth speed. but what about 4 drives? using a raid enclosure over usb3 should be ok but cheap enclosures have flaky raid controllers; on the other hand do you think software raid over the… Read more »

@memeka Well, I’m not a fan of RAID used with SBC anyway (RAID is about availability and too much components are simply a Single Point of Failure here) and the XU4 is clearly not the device I would choose if I would’ve to implement RAID with more than 2 disks. Anyway: The SoC’s 2nd USB3 host port is connected to an internal GL3521 hub which features 4 downstream ports but only two are exposed on XU4. So to use more than 2 USB3 disks it’s necessary to cascade hubs (no idea whether USB Attached SCSI is then still working, I… Read more »

@tkaiser if building a NAS obviously the first thing to avoid is cascading hubs – that’s why i said to use just 1 USB3 port (didn’t know about the 2 downlink channels). hence the use of USB3 external encosure with how-many-drives-you-want. i also agree USB-RAID sucks – and not just because you lose everything when the controller dies – but for software RAID, do you think the performance is heavily affected by the increase in overhead? e.g. with USB-RAID, the board will see 1 drive, so there’s 1x overhead of commands; with software RAID the board will see 4 drives,… Read more »

Not UAS capable, limited SAT support (you’d have to use ‘-d sat’ with smartctl), horrible performance with a software RAID-0 (especially random IO), totally unreliable (disks spinned down even if in use). Those JBODs in USB mode do either use special bridge chips or use SATA multiplexer or maybe even internal Hubs and individual USB-to-SATA bridges. Depends on the model used, so always… Read more »

Btw, espressobin is a bit lacking:
2xa53 is not enough, I would want to run some other servers and some java (e.g. FileBot)
2gb ram is enough, but price is high for that option
1 sata only
on pcie they provide wifi; i heard sata on mpcie have issues on some socs so until it’s been tried thoroughly I am skeptic – also there are no 4x sata mpcie and a total of 3xsata is not enough

I asked them last Friday if they are thinking about a new oDrod XU. I ordered one 2 weeks ago and I already managed to brick with a 5V UART adapter (I was told that it has 3.3V). Now I am little sceptical to order a replacement, because I would love to have a newer (possibly) more powerful oDroid. But I will most likely order another one tomorrow from hardkernel.com.

Why should Hardkernel come up with a more ‘powerful’ new board now selling XU4 remainders off? An ODROID-C3 based on Amlogic’s S912 with 3GB DRAM will keep customers happy since they only buy numbers (still octa-core but more DRAM, hey what else to consider?!)

@Memeka Well, ESPRESSOBin is way better suited for a NAS than any other SBC since the Marvell SoCs are made for bandwidth. I tested one ASM1062 with my Clearfog Pro (‘only’ dual Cortex-A9 but here for example Marvell’s CESA crypo extensions can be used) and it works (tested only with a 3.5″ HDD). Also the SoC supports 2.5GbE downstream to the internal TOPAZ switch so if that board serves 3 clients overall bandwidth is much higher than Gigabit Ethernet (and yes, it’s already reported from Clearfog boards that Marvell SoCs have no problem to saturate 2.5GbE while also saturating 3… Read more »

I guess something that could work is firefly 3399 – 2xa72+4xa53, 2/4gb ram, gb eth and 2xpcie – so u can have 4xsata. If it supports port multiplication, even more, although it lowers the bw.
It should work nicely with zfs (64bit) and 2xsata per pcie port – although for gb eth nas I think you can add up to 5 sata/pcie safely (I’m assuming 500MB/s pcie and each hdd would have 100MB/s).

There are new chips from Samsung, they could find new hardware. I got a reply from them this morning, they are not planning to produce a replacement for XU4 any time soon. I wonder if the higher price is the main issue in releasing a new board. The XU4 is a good and powerful board as it is.

Sadly I do think I fried it with the 5V UART adapter. There is not overvoltage protection on the IO pins, only on the power plug. I found a few others with the same issue as mine. The blue power LED is lighting up, not the red one (that shows that the target has booted and started). I really, really wish I could fix it, but I think I cannot, sadly 🙁 If you or anybody else has an idea, please let me know, because their site has issues with payment and I did not order a replacement yet.

The SoC is simply made for NAS+RAID 😉 But I still wouldn’t rely on this sort of ‘hardware RAID’ then (at least without having each SPoF lying around separately since otherwise RAID becomes a bad joke). We switched to ‘software RAID’ even in large installations in the meantime. Last storage cluster implemented at a customer providing 48TB net is made of… Read more »

I have Marvell-based nas and I agree marvel is best for this – it’s just not working for me because I want VPU for transcoding. Hence looking at others.
I am looking forward to performance numbers from firefly, but on paper it looks ok for home nas – having 3-4 simultaneously users saturating a gb connection.
