Features：
● High performance. The RK3288 chip uses a quad-core ARM Cortex-A17 architecture, the main frequency can be as high as 1.8GHz, compared with the single-core, dual-core, and quad-core solutions common in the market. It has a qualitative leap in performance, can play high-definition video in various formats, and can handle complex interactive operations.
● High stability. RK3288 Android integrated board, in hardware and software, add your own unique technology to ensure the stability of the product, can make the final product 7 * 24 hours unattended.
● High integration. RK3288 Android integrated board integrates Ethernet, EDP, Wi-Fi, power amplifier, TF expansion card, USB expansion port, IR remote control function, HDMI, LVDS, backlight control, microphone and other functions, greatly simplifying the overall design.
● High scalability. SIX expansion USB ports (4 ports are PIN type, 2 ports are standard type), 2 serial ports + 1 expandable debug serial port, five IO expansion ports can expand more peripheral device.
● High definition. Supporting various LVDS / EDP / HDMI interfaces and cropping screens of various sizes and resolutions.
● Perfectly support multiple mainstream touch screen functions such as multi-point infrared touch, multi-point capacitive touch, multi-point nano film touch, multi-point acoustic wave touch, multi-point optical touch, etc.
