Rövid leírás:

Az ODROID-M1S SBC (single board computer), a korábbi M1 típus kompaktabb változata több GPIO portot, kisebb fogyaztást és több tartozékot hozott. Az ODROID-M1S esetén is a SoC (System on Chip) gyártója, a Rockchip garantálja az ellátást a következő 15 évre, ezért úgy tervezhetünk, hogy az ODROID-M1 lapokat a B2B ügyfeleink számára 2036-ig vagy azt követően is tudjuk majd szállítani.

A Home-Assistant OS a 12. verziótól ezt az alaplapot is natívan támogatja, így nagyon egyszerűen telepíthető rá kedvenc okosotthon platformunk. Az alábbi leírásban található megoldás a belső eMMC-re történő telepítéshez: https://github.com/home-assistant/operating-system/blob/dev/Documentation/boards/hardkernel/odroid-m1s.md

CPU
Az M1S SoC az RK3566 az eredeti M1-ben használt RK3568 kistestvére. Ez segíti a szoftverfejlesztés nagy részének újrafelhasználását. A rendszerbetöltő és a kernel beállításai eltérőek, az M1 meglévő operációs rendszer image-ek nem használhatók úgy, ahogy vannak, de a portolás gyorsan, egyszerűen lehetséges.

eMMC:
Az ODROID sorozatban először az eMMC chip a PCB-re van forrasztva, így nem cserélhető. A gyártó úgy látja, hogy 64 GB kapacitás elegendő a legtöbb beágyazott rendszer építéséhez.
Az eMMC sebessége a fio paranccsal mérve körülbelül 180 MB/s, ami körülbelül 3-5-ször gyorsabb, mint a tipikus microSD kártyáké.

M.2 NVMe foglalat
Ha a beépített eMMC memória 64 GB-os tárhelye nem elegendő, egy szabványos, 2280-as formátumú NVMe SSD használható.
Az eredeti M1 modell PCIe 3.0 x 2 sávos konfigurációjától eltérően az M1S PCIe 2.1 x 1 sávos konfigurációval rendelkezik. Az M1S NVMe átviteli sebessége körülbelül 1/4-ével csökkent, ez kb. ~400 MB/s átviteli sebbeséget jelent.
M.2 SATA tárolóeszközök nem használhatók! Az M.2 slot csak PCIe interfészt (M-Key) támogat.

Termékleírás

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.

 

 

MIPI-DSI

-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.

 

 

 

 

NPU

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 : https://commons.wikimedia.org/wiki/File:Traffic_in_Brasilia_before_Brazil_%26_Chile_match_at_World_Cup_2010-06-28_1.jpg )

 

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.

Conf=0.25 CPU (ms) NPU (ms) NPU: Cam (fps)
M1S 1288.3 70 11.8
M1 1225.7 64.3 13
