A High-performance & High-efficiency Platform For 4K UHD Streaming

3.5″-SBC-R390 is a 3.5″ single board computer powered by Rockchip RK3399 processor based on ARM® big.LITTLE architecture with ARM® Cortex®-A72 (big) and Cortex®-A53 (LITTLE). The “big” Cortex®-A72 core is designed to execute high-performance tasks while the “LITTLE” Cortex®-A53 core is designed for high-efficiency tasks. Based on this hybrid architecture, 3.5″-SBC-R390 can automatically handle the allocation of tasks to the appropriate cores according to the performance required. In addition, with 4K Ultra HD video decode capabilities as well as DP and HDMI 2.0 output interfaces, it delivers optimized performance in 4K Ultra HD streaming at 60 fps with the lowest power.

Ideal For Fanless & Budget-conscious System Integration

3.5″-SBC-R390 is an ideal platform for integration into a fanless system used in budget-conscious consumer, commercial or industrial applications, such as home entertainment, digital signage, kiosk, smart office, smart surveillance and industrial control.
