ODROID-M2 with 8GByte RAM

The ODROID-M2 is a standout high-performance single-board computer (SBC) compared to the M1 series.

We introduced the ODROID-M1 around two years ago, followed by the ODROID-M1S a year later. Both models have been well-received and continue to serve as essential components in embedded systems for our B2B clients.

While feedback indicated that the performance and I/O port configurations of the ODROID-M1 and M1S met the needs of most embedded systems, some customers expressed a desire for higher-end models featuring more powerful processors. In response to the demand for enhanced computing capabilities from key industrial embedded system developers, we are excited to announce the launch of the new ODROID-M2 SBC today.

Compared to the original ODROID-M1, which is based on the RK3568B2 SoC, the ODROID-M2 features the more advanced RK3588S2 SoC, offering the following enhancements:

With its high-speed 64-bit LPDDR5 memory and powerful GPU, the ODROID-M2 delivers impressive graphics performance in a 4K dual-head display setup. We connected two 4K monitors via the HDMI port and the Alt-mode USB Type-C port. This demonstration showcases 4K 3D rendering utilizing hardware GPU acceleration on the first monitor, while the second monitor handles 4K video playback with hardware VPU acceleration. Thanks to the efficient use of hardware accelerators for demanding graphics applications, the cooling fan operates infrequently, as the system generates minimal heat.

• Multiprocessing performance: Approximately three times faster.
• RAM: LPDDR5 64-bit RAM with over twice the memory bandwidth.
• GPU: More than five times the performance of the previous model.
• NPU: More than three times faster.
• Storage: An onboard 64GB eMMC storage device, now twice as fast thanks to the HS400 interface.

The RK3588S2 SoC with multiple high-performance CPU/GPU cores and large cache memory blocks, is manufactured in the Samsung Foundry’s 8N process, and has the advantage of relatively low power consumption compared to performance.

On-board M.2 NVMe Slot

If the 64GB of soldered eMMC memory isn't enough, you can expand your storage using an industry-standard M.2 2280 form factor NVMe SSD. The board features an M.2 NVMe slot for accessing larger data storage capacities.

While the ODROID-M2 utilizes a PCIe 2.1 x 1 lane configuration—compared to the original M1's PCIe 3.0 x 2 lanes—this results in a reduction of NVMe transfer speeds to approximately 1/4 of the original. However, we still find that a storage access speed of around 400 MiB/s is adequate for developing various high-end embedded systems. Please note that M.2 SATA SSDs are not supported; the M.2 slot is compatible only with PCIe SSDs (M-Key).
