As edge computing demands grow more complex, developers and product engineers need compute modules that can keep up — without compromising on I/O flexibility, thermal performance, or multimedia capability. The MST35885 from DIT (Hunan Display Innovation Technology) is a System-on-Module (SOM) built around the powerful Rockchip RK3588 octa-core processor, bringing enterprise-grade computing power to a compact, board-ready form factor.
Whether you're building a smart kiosk, a computer vision node, a server cluster endpoint, or an industrial display terminal, the MST35885 is worth a serious look.
What Is a SOM?A System-on-Module (SOM) integrates the core computing elements — processor, memory, storage, and key interfaces — onto a single compact PCB. Paired with a custom carrier board, it dramatically reduces hardware development time. Engineers can design their product-specific I/O and form factor on the carrier while relying on a certified, production-ready compute module for the "brain."
The MST35885 follows this philosophy perfectly.
Processor: Rockchip RK3588 Octa-CoreAt the heart of the MST35885 is the Rockchip RK3588, one of the most capable application processors available for embedded and edge applications today.
The RK3588 features a dual-cluster CPU architecture:
- 4x ARM Cortex-A76 high-performance cores
- 4x ARM Cortex-A55 efficiency cores
This big.LITTLE design allows the system to dynamically balance compute-intensive tasks with energy-efficient background workloads — ideal for applications that need both responsiveness and low idle power.
The GPU is an ARM Mali-G610 MC4, supporting:
- OpenGL ES 1.1 / 2.0 / 3.1 / 3.2
- Vulkan 1.1 and 1.2
- OpenCL 1.1, 1.2, 2.0
The RK3588 also includes a High Performance NPU (Neural Processing Unit), making it capable of running AI inference workloads locally — an essential feature for computer vision and on-device ML pipelines.
The MST35885 ships with 4GB LPDDR4 RAM, upgradeable to a maximum of 32GB, providing headroom for memory-intensive applications like multi-stream video processing or large inference models.
Storage starts at 32GB eMMC, expandable up to 256GB. The eMMC 5.1 interface ensures fast sequential read/write performance compared to older storage standards.
Operating System SupportThe MST35885 supports:
- Android 12
- Ubuntu 20.04 (with Euler access support)
This dual OS support makes it versatile across both consumer-style touchscreen applications and Linux-based industrial deployments.
Display and Multimedia: Where the MST35885 ShinesOne of the most compelling aspects of the MST35885 is its rich display and multimedia capabilities, powered by the RK3588's integrated media processor.
Display Output- Multi-screen support up to 4096×2160 resolution
- Dual-channel MIPI-DSI (4 lanes per channel) or CPHY 1.1
- 2× HDMI/eDP TX supporting HDMI 2.0 (up to 6Gbps), HDMI 1.4b, HDCP 2.3 and 1.4
- eDP at 4K@60Hz with HDCP 2.3 and DSC 1.1/1.2a
- DP 1.4 supporting up to 7680×4320@30Hz
The onboard media engine handles:
- H.265 / H.264 at 8K@60fps
- AV1 at 4K@60fps
- VP9 / AVS2 at 8K@30fps
- MPEG-2/-1 / VC-1 / VP8 at 1080P@60fps
This makes the MST35885 an excellent choice for digital signage, video surveillance aggregation, and professional display terminals.

The 4× MIPI CSI camera inputs are particularly noteworthy for computer vision builds — you can connect multiple cameras simultaneously for multi-angle capture, stereo vision, or parallel inference pipelines.
Connector SystemThe MST35885 uses a high-density BTB (Board-to-Board) connector system:
- 3× 80-pin Male BTB connectors (DF12NA(3.0)-80DS-0.5V series)
- 1× 100-pin Male BTB connector (DF40C-100DP-0.4V series)
This connector layout distributes all high-speed signals (PCIe, HDMI, MIPI) cleanly across dedicated connectors, reducing signal crosstalk and simplifying carrier board design.
