The ODROID H-series is growing with three brand new models

Again, the new generation is more powerful and offers higher performance. 
It also delivers key new IO that will please many users.

Introducing the ODROID-H4, H4+ and H4 Ultra

Hardkernel is introducing the ODROID-H4, H4+ and H4 Ultra, which is equipped with higher performance and richer interfaces.


The major characteristics of the ODROID-H4 series compared to the ODROID-H3 series are:

  1. Faster CPU architecture Alder Lake N vs. Jasper Lake. Plus AVX2 extensions.
  2. Faster DRAM interface DDR5 4800 MT/s vs. DDR4 2933 MT/s.
  3. Higher base and boost CPU frequencies and more powerful iGPU.
  4. The increase from 2 to 4 SATA ports allows connection to a greater number of storage devices, ODROID-H4+ and ODROID H4 Ultra only.
  5. An additional DisplayPort added allows the simultaneous use of up to 3 monitors.
  6. Low cost ODROID H4 for compute and graphics applications (e.g signage, robot, factory automation,..)
  7. Flagship H4 Ultra doubling the number of CPU cores, from 4 to 8 cores.

We also implemented little details following the ODROID-H3 feedback we receive from all of our users, this means you. Examples: 

  1. Dual BIOS: If the BIOS is corrupted due to a power outage during update, etc., you can boot into the backup BIOS and recover by moving the jumper next to the DC jack. This feature is only available on ODROID-H4+ and ODROID H4-Ultra.
  2. The new H4 cases format has been improved so that a cooling fan can be mounted inside the case.
  3. A Mini-ITX kit for seamless integration with generic ITX PC cases.

Let’s look at the detailed table shown below.

Noteworthy Features

Why the N97 instead of the N100?

Bigger numbers aren’t always better. INTEL naming may be deceiving.

We chose the N97 because its Maximum Turbo Frequency is 200MHz higher than the N100, respectively 3.60GHz vs. 3.40GHz. In addition, the GPU Max Dynamic Frequency is a whopping 450MHz higher, respectively 1.2GHz vs. 750MHz.

The TDP value of the N97, which is therefore faster than the N100, is higher, but there is almost no difference in power consumption at idle state. Although the N97 is more expensive, we chose it for its higher performance.

Single-Channel Memory

This is a decision made by Intel. The Alder Lake N processors only offer one single-channel of memory. However, the DDR5 speed of 4800 MT/s as well as the Dual Rank (r2x8) option largely compensate for the double-channel of DDR4 with the H2 and H3 series. The DDR5 4800 MT/s of the H4 series leaves the DDR4 2933 MT/s and DDR4 2400 MT/s of the H3 and H2 series in its rear mirror.

Note: While the Intel ARK pages specify the Alder Lake N max. memory to be 16GB, we validated that 32 and 48 GB DDR5 SO-DIMMs 4800 or 5600 MT/s work as well. The 5600 MT/s will run at 4800 MT/s. The Intel specifications for the H2 and H3 processors were limited as well, but many users were able to (respectfully) pump up the max. memory to 32 and 64 GB.

How many SATA ports and video outputs?

Compared to the previous generation Gemini Lake or Jasper Lake, the design flexibility of the new Alder Lake-N’s high-speed signal interface has been significantly reduced. To enable SATA ports inside the SoC, a choice arose: reducing the number of PCIe lanes for NVMe from 4 to 2 or find another way. In order to avoid compromising the speed of NVMe, it was inevitable to add an external, expensive SATA controller.

Thanks to a controller that supports four SATA ports, the requirement to connect many storage devices has been resolved. As the performance of CPU, GPU, and DRAM increases, it has become possible to drive a large number of displays. Therefore, in addition to the one output each for HDMI and DisplayPort in the existing H series, the new H4 series is equipped with an additional DisplayPort, allowing a total of three 4K monitors to be connected simultaneously.

Because there are more connectors with relatively large footprints, the form factor has changed from 110x110mm to 120x120mm, and the area has increased by about 20%. As a result, form factor compatibility with the existing H2/H3 series has unfortunately disappeared. However, this affects only the case compatibility. Accessories such as the Net Card work on H2, H3 and H4 series.

Which H4 model is the best for you?

To allow you to use a high-performance platform at a relatively low cost, we removed all SATA functions, the second Ethernet port, and the Dual-BIOS feature to create a basic H4 model that focuses on cost-effectiveness. Therefore, it is suitable for application to embedded systems such as digital signage or factory automation or robot control.

On the other hand, the H4+ is equipped with four SATA ports, a second Ethernet port, and Dual-BIOS feature, making it the best choice for users who need mass storage for high-performance NAS and/or use it for routing capabilities.

Finally, although it is more expensive, we have also designed the H4 Ultra model, which can take advantage of powerful performance with twice the number of CPU cores (from 4 to 8) and more GPU execution units. Thanks to its many cores and fast clocks, the H4 Ultra model shows computing performance that can be twice as high as the H4 and H4+ models, based on multithreaded computing benchmarking results.

If you are very sensitive to power consumption, the H4 model would be the most desirable option. This is because the power in idle state is about 1 Watt lower than the H4+ model.


Thanks to the Intel Alder Lake-N Gracemont architecture, the higher frequencies of the N97, for the H4 and H4+, and N305, for the H4 Ultra, coupled with DDR5 4800 MT/s, the H4 and H4+ in UP mode are on average around 36% more performant than the H3+ in UP mode. The increased performance jumps to around 83% for the H4 Ultra, again compared to the H3+ in UP mode. This is what we witnessed while running 206 mostly non-synthetic benchmarks. We review these benchmarks further down. We will also see that the increased performance climbs to even higher numbers for multi-threaded applications.


For the last 4 years, We acquired a lot of experience and feedback from users, meaning you, first with the H2 series, then with the H3 series. We have seen and still see an incredible broad range of applications.

Some users pushed their ODROID to the max with as much memory as possible, disks, discrete graphics cards, additional SATA ports cards or high-bandwidth network cards.

Conversely, other users made their ODROID as frugal as possible, chasing the last tenths of Watt that could be saved. In this matter, see section Power Consumption Characteristics, we worked on many aspects to make significantly low idle power consumption possible, as well as documenting and enabling users to know how to reach idle power that is not at all high compared to ARM series
boards. We believe this is essential, especially for European users where the cost of electrical energy has been rising for years, to which you add the goal of reducing net greenhouse gas emissions, as targeted by the EU, while running 24×7 systems.

These two extremes, and everything in the middle, are possible because the H series boards can be widely customized. We believe the success of the ODROID H-series is in part due to its original DIY design goal with boards that do not restrict you to one kind of application, e.g. TV box.

The ODROID H4 series doubles down on versatility by adding the low cost H4, with stripped down hardware, on one side of the H4+, and the 8-core H4 Ultra flagship on the other side of the H4+.

The table shown below details the H4 series user-level customizations:

Design An SBC design that makes sense: all the connectivity is on the rear side, simplifying case design and reducing footprint on a desk.
H-series Net Card Using the NVMe port, provides 4 additional 2.5 GbE ports, thus tripling the number of 2.5 GbE ports to 6 ports.
Do It Yourself The ODROID H-series offers you a lot of freedom. You are free to chose:

1. The amount and brand of memory. No soldered memory.

2. The size of the eMMC (including not using one). No soldered eMMC.

3. The size of the NVMe PCIe Gen 3 x4 SSD, including not using one(*).

4. To transform the NVMe slot into a PCIe Gen 3 x4 slot for using PCIe cards via optional adapter cable(*).

5. The size of the 1 to 4 SATA III hard disks or SSDs, including not using them (H4+ and H4 Ultra only).

6. A case among 4 (soon to be 5) types of Hard Kernel cases or use a custom one you design or another user designed or use a mainstream Mini-ITX case thanks to the ODROID H4 Mini-ITX kit.

7. Hard Kernel cases allow the usage of an optional silent fan for optimal thermal performance.

8. Any x86-64 flavor of Windows, Linux or BSD operating systems, etc.

9. To upgrade the hardware later with larger memory, more NVMe or SSD or hard disk space.

10. To maximize performance or to minimize power consumption thanks to well documented BIOS and OS options.

(*) PCIe Gen 2 on the H2/H2+.


Note: This summary compares the UP versions of the H3+, H4, H4+ and H4 Ultra because we did not run all the benchmarks on the H3+ non-UP. We ran a total number of 206 benchmarks/cases using the UP configurations.

The major facts about these benchmarks are:

  • The H4 and H4+ UP are on average around 36% more performant than the H3+ UP.
  • With the H4 Ultra UP, the average climbs to around 83%!
  • The H4 and H4+ UP can be up to twice faster than the H3+ UP for particular tests.
  • The H4 Ultra UP can be up to three and a half faster than the H3+ UP for particular tests.
  • The H4 Ultra UP is on average around 36% more performant than the H4 and H4+ UP.
  • The H4 Ultra UP can be more than twice faster than the H4 and H4+ UP for particular tests.
  • Not too surprising, with 8 cores vs. 4 cores, the H4 Ultra UP top performance occurs with multi-threaded applications
    (e.g. Compilation, Java, Imaging, Stargate, MemCached, OpenSSL, Video Encoding,…) without being kneecapped by thermal throttling, thanks to Unlimited Performance and active cooling.

UPS Kit for M1S


The UPS(Uninterrupted Power Supply) Kit is designed specifically for the ODROID-M1S.

It is equipped with a 18650 rechargeable Li-Ion battery holder, charger control IC and a 5Volt Boost DCDC. There is a small MCU on the board which measures the battery level and communicate with the ODROID-M1S board via USB interface. When the AC power source is removed, the UPS keeps supplying the power to the ODROID-M1S boards with the battery.

The M1S-UPS has a USB serial port(ttyACM) to communicate with so that it can trigger the shutdown process by sending a low battery warning. It will significantly reduce the risk of data loss by sudden power loss.When the AC power source becomes available again, the UPS will supply power to the ODROID-M1S again and trigger a power-on event automatically.

✔ The battery is not included in the package, so you have to buy a PROTECTED 18650 Li-Ion rechargeable battery in your local market and install it. The length of the 18650 Li-Ion battery with a built-in protection circuit is close to 68mm, which is about 3~4mm longer than the unprotected bare cell battery length of 65mm.

  • Since the retail market in many countries, including South Korea, does not allow the sale of unprotected lithium-ion rechargeable batteries, we designed it to use batteries that include a protection circuit.
  • For safety reasons, when purchasing batteries, please choose a reputable battery cell manufacturer if possible. As far as we know that Panasonic, LG, Samsung, and CATL are famous.

✔ Due to the Li-Ion chemical characteristics, the battery voltage level might go higher slightly when the load is very light.

We launched ODROID-M1 about 20 months ago and have supplied it to many B2B and B2C customers. Feedback from many customers requested a lower price, more GPIO ports, lower power consumption, a slimmer form factor, and a variety of practical peripherals.

We would like to introduce you to the ODROID-M1S which was developed over the past six months to respond to market demands.
We made the board about 20% thinner, reduced power consumption by about 20%, added 14 header pins, and a built-in 64GB eMMC chip on the board. We have lowered the price to only $49 including a case, heatsink, and power adapter. We believe this will help significantly reduce the cost of building your own affordable and sustainable embedded systems. To ensure longevity, which is important to customers using it for industrial purposes, we will supply this product until at least 2036.

By utilizing 3D modeling from the early PCB design stage, we were able to complete case development relatively precisely and rapidly. It will be remembered for a long time as a novel development project in which collaboration between circuit design & mechanical design proceeded quite smoothly.

M1S PCB 3D model 

The SOC in the M1S is the RK3566, which is the younger sister of the RK3568 used in the original M1. This allows most of the software development to be reused. Because the bootloader and kernel settings are different, existing OS images for M1 cannot be used as-is, but porting is quickly possible through a simple process.

For detailed internal configuration, please refer to the block diagram below.

On-board eMMC storage

For the first time in the ODROID board series, an eMMC chip was soldered to the PCB by default instead of using a removable eMMC module. We think 64GB capacity is sufficient for building most embedded systems. The speed of eMMC measured with the fio command is approximately 180MiB/s, which is about 3~5 times faster than typical microSD cards.

On-board M.2 NVMe slot

In case the 64GB storage space of the soldered eMMC memory is insufficient, consider using an industry standard 2280 form factor NVMe SSD. An on-board M.2 NVMe slot is provided to access large amounts of data storage. Unlike the original M1 model’s PCIe 3.0 x 2 lanes configuration, M1S has PCIe 2.1 x 1 lane. The NVMe transfer speed of the M1S has been reduced by about 1/4. However, we still believe that ~400 MiB/s of storage access speed is sufficient for building various high-end embedded systems.
Note that M.2 SATA storage devices can not be used. The M.2 slot supports only a PCIe interface (M-Key).

Power consumption

To create the graph below, we turned on the M1S and recorded the power consumption until the Ubuntu Desktop OS boots and enters Idle mode. We used the SmartPower3 device to examine power characteristics.
-With Ethernet and HDMI monitor connected, the peak power consumption is close to 3.7 Watts during booting, but drops to 1.5 Watts in desktop GUI idle state.
-If you remove the HDMI monitor for a headless system, power consumption in idle mode drops to near 1.0 Watt. Additionally, please note that when the Ethernet cable is unplugged, the power drops to 0.7 Watt.

When performing a CPU stress test without either HDMI output or Ethernet connection, the power consumption is about 3.2 Watts. This shows an energy savings of about 25% compared to the 4.3 Watts of the original ODROID-M1 under the same test conditions. Note that the computing power of ODROID-M1S has been measured to be 5-10% lower than that of M1.

Thermal Characteristics

Thermal throttling does not occur even when performing a CPU stress test while mounted in a case. Because system power consumption is low, less heat is generated. Cooling is sufficient with just the stock heatsink.
As shown in the graph below, when a stress test was performed on ODROID-M1S with a stock heatsink under room temperature conditions of 25°C, the CPU temperature did not exceed 65°C and maintained the maximum clock frequency.

Even when assembled in the case, the CPU temperature did not exceed 75°C and thermal throttling did not occur.

-The CPU has four ARM Cortex-A55 processors with low power consumption & high efficiency operation at 1.8Ghz. A larger 8GB of LPDDR4 DRAM memory is available in addition to a 4GB model for reduced cost.

GPIO Header

There are 40-pin and 14-pin header pin connectors for general purpose input and output functions. Digital IOs, UARTs, I2Cs, PWMs, ADCs, SPI, USB 2.0 host, Analog audio output, Power-on and Reset signals are available.
What we heard from many B2B and B2C customers is that they often didn’t use the actual GPIO functionality. Therefore, to lower production costs and product price, we decided to make GPIO header pin installation an option. If you choose the option to install 40-pin and 14-pin GPIO headers, $3 will be added to the price. An IO-labels board for easier DIY tinkering will also be provided.


-The four-lane MIPI-DSI port can be directly connected to an LCD panel.
-The ODROID-Vu8S kit with an 8 inch, 800×1280 wide viewing angle LCD and capacitive multi-touch screen is an available option. Note that LCD connector is different from the one on the ODROID-M1.
-If you assemble the ODROID-M1S single board computer on the rear side of the Vu8S kit, you can easily implement a Human-Machine-Interface (HMI) device with Android as well as Linux.


Since Machine Learning has been a trend in this industry, there is a neural network processing unit (NPU) which can deliver up to 0.8 TOPS on the M1S single board computer. We could run various TensorFlow Lite and ONNX models on Ubuntu Linux OS. Here is an example of object detection.

– Input image and Output image ( The input image source : )


As shown in the test results below, the object detection speed of the NPU is nearly 20 times faster than that of the CPU. For reference, the NPU performance of M1S is about 10% lower than that of M1. We believe this is due to the difference in DRAM clocks.
