Purpose& Description
RK3328 Core Board adopts the RK3328 processor, which is a Cortex A-53, quad-core, 64-bit chip. It can be paired with multiple types of DDR3 and DDR4 RAM. Moreover, the Rockchip processor offers an onboard MALI-450MP4 GPU and a multi-media processor expressly designed to encode and decode 1080P and 4K Video streams and high-quality audio streams – perfect for commercial/industrial applications that will have customer and public-facing software. Onboard HDMI support also eases graphics software and hardware integration.
