3.5”-SBC-R39

3.5" SINGLE BOARD COMPUTER WITH ARM® CORTEX®-A72 + CORTEX®-A53 BASED PROCESSOR, ROCKCHIP RK3399(K)

3.5"-SBC-R39 is a 3.5" single board computer powered by Rockchip

RK3399(K) processor based on ARM® big.LITTLE architecture with

ARM® Cortex®-A72 (big) and Cortex®-A53 (LITTLE), which delivers

optimized performance in 4K Ultra HD streaming at 60 fps with the

lowest power. It is an ideal platform for integration into a fanless

system used in budget-conscious consumer, commercial or indus-

trial applications, such as home entertainment, digital signage,

kiosk, smart oce, smart surveillance and industrial control.
