ODROID M1S 4GB with Case and EU Power Supply
Downloads
The ODROID M1S is an improved version of the ODROID M1 that has been designed considering the feedback from the B2C and B2B customers. Hardkernel has come up with the cost-effective ODROID M1S board with more GPIO ports (40 + 14 Pins), a slimmer form factor, and lower power consumption. The M1S is 20% thinner than the ODROID M1 and consumes approximately 20% less power than its predecessor. Additional 14 GPIO pins have been added and there is also a 64GB eMMC chip onboard.
Please note that the GPIO Pin Headers are NOT included.
The ODROID M1S comes with the official Hardekernel case, Heatsink, and Type-C power adapter (EU plus on this version). Hardkernel promises the supply until at least 2036.
RockChip RK3566 SoC 1.8GHz Quad-Core
ODROID M1S has the RK3566 System-on-Chip (SOC). Designed as the successor to the original M1, the M1S inherits compatibility with most existing software developments while incorporating improved hardware specifications.
The M1S is equipped with a quad-core ARM Cortex-A55 CPU operating at 1.8GHz, creating a balance between low power consumption and high operational efficiency. This version is available with 4GB LPDDR4 RAM, catering to diverse computing needs while maintaining cost-effectiveness.
Neural Network Processing Unit (NPU)
In response to the industry trend towards machine learning, the M1S integrates a Neural Network Processing Unit (NPU) capable of delivering up to 0.8 TOPS. This empowers users with enhanced capabilities for machine learning applications.
Display Connectivity
Featuring a 4-lane MIPI-DSI port, the M1S provides direct connectivity to LCD panels. The optional ODROID-Vu8S kit, equipped with an 8-inch, 800×1280 wide-viewing-angle LCD and capacitive multi-touch screen, offers an ideal solution for Human-Machine Interface (HMI) development with support for both Android and Linux operating systems.
On-board Storage Solutions
For the first time in the ODROID series, the M1S integrates a default eMMC chip directly soldered to the PCB, offering 64GB of storage capacity. With a speed of approximately 180MiB/s, the eMMC outperforms typical microSD cards by 3 to 5 times, ensuring efficient data access for embedded systems.
Expansion Capabilities
To accommodate larger storage needs, the M1S includes an on-board M.2 NVMe slot supporting industry-standard 2280 form factor NVMe SSDs. While the transfer speed is reduced compared to its predecessor, reaching ~400 MiB/s, it remains ample for various high-end embedded systems.
It is important to note that only PCIe interface (M-Key) NVMe SSDs are supported, and M.2 SATA storage devices are incompatible.
Power Efficiency
The M1S demonstrates commendable power efficiency with a peak consumption of around 3.7 Watts during booting, dropping to 1.5 Watts in desktop GUI idle state with Ethernet and HDMI monitor connected. For headless systems, idle power consumption further decreases to nearly 1.0 Watt. Unplugging the Ethernet cable results in an additional power drop to 0.7 Watt.
