The LKD3399 Single Board Computer SBC is a multifunctional industry application board meticulously designed based on the Rockchip RK3399 chip platform, consisting of our company’s LCB3399 system on module and baseboard. The core module is connected to
the baseboard through a B2B connector and is securely fastened with four M2 screws, ensuring stability and reliability. The board is versatile in functionality, rich in interfaces, compact in size, and thin and flat, making it suitable for products with limited structural space.
The LKD3399 Single Board Computer SBC features four USB 3.0 and two USB 2.0 interfaces, allowing for the connection of multiple USB
cameras; it has two AHD camera input interfaces for simultaneously connecting two AHD cameras; and a mini-PCIe interface that, in addition to connecting a 4G module, can also connect to our company’s mini-PCIe interface NPU computing card based on the RK1808, forming an artificial intelligence vision computing card that
supports 3.0TOPS computing power in combination with multiple cameras;
Moreover, LKD3399 Single Board Computer SBC also supports dual-band WIFI, BT5.0, 1000M Ethernet, UART, RS232, RS485, and other commonly used communication module interfaces, and supports a variety of display interfaces such as HDMI, eDP, MIPI, dual-channel LVDS, and multi-screen display. The LKD3399 Single Board Computer SBC supports Android, Linux, and Ubuntu systems, offering advantages such as high performance, high reliability, and high scalability, and provides users with open system source code. Users can develop and customize based on this product, and our company provides comprehensive technical support for developers and enterprise users, enabling them to efficiently complete research and development work and significantly shorten the product
development and mass production cycle.
