Hexa-core 64-bit processor

RK3399, a hexa-core 64-bit (A72 * 2 + A53 * 4) high-performance processor, features a frequency of up to 2.0 GHz and a quad-core
Mali-T860 GPU. Multiple storage configurations are available, enabling users to rapidly advance project development by extending

Accelerate image recognition with dual ISP

Dual ISP, capable of processing at a maximum of 13 MPix/s for a single input or dual 8 MPix/s, supports simultaneous input from two
cameras. It enables advanced functions such as panoramic capture, gesture detection, depth sensing, and 3D processing, accelerating
image recognition.

4K HD video decoding

This mainboard supports 4K VP9 and 4K 10-bit H265/H264 60fps video decoding and is equipped with video post-processing functions,
including deinterlacing, noise reduction, and edge/detail/color optimization. It also supports 1080P (H.264, VP8) video encoding.

Multiple display interfaces

With MIPI, dual LVDS, eDP 1.3, and HDMI 2.0, it enables dual-screen output with the same or different displays.

Strong network communication capability

It is equipped with a 1000Mbps RJ45 Ethernet, dual-band 2.4 GHz/5 GHz WiFi (802.11a/b/g/n/ac protocols and 2 * 2 MIMO technology), and
Bluetooth 4.1. It also supports the expansion of 3G/4G LTE through the Mini-PCIe interface, enhancing network communication speeds.

Extensive connectivity

A wide range of interface options includes M.2 PCIe, RS485, RS232, MIPI-CSI, MIPI-DSI, USB 3.0, USB 2.0, LINE-IN, I2S, I2C, SPI, and UART.
