Introduction to the core board：
RK3128CV4 is a cost-effective core board based on Rockchip RK3128. It is a low-cost A7 quad-core
, High cost performance core board with main frequency 1.3GB. RK3128 integrates Mali-400 MP2 graphics processor, supports OpenGL ES1.1/2.0, embedded high-performance 2D hardware acceleration, and can achieve 1080P H.265 video hard decoding and H. 264 video encoding, and Antutu runs more than 14000 points, with good performance, and its extremely low cost highlights its super high cost performance.
The RK3128CV4 core board is widely used in human-computer interaction, intelligent control systems, portable handheld projectors, set-top boxes, medical, automotive, POS and other fields. It is especially suitable for cost-sensitive application scenarios with high performance requirements.
