The OrangePi 4 Ultra features the Rockchip RK3576 octa-core 64-bit AIoT processor (4×Cortex-A72 @ 2.2GHz + 4×Cortex-A53 @ 1.8GHz), supporting multi-tasking parallel processing and high-performance computing.
It integrates a 6 TOPS NPU that supports mixed-precision operations in INT4/INT8/FP16, enabling smooth execution of edge-side large models such as ChatGLM and Qwen.
Onboard LPDDR5 memory and FSPI NOR FLASH deliver faster system boot times and data read/write speeds; supports eMMC/UFS modules, NVMe SSDs (PCIe 2.0), and TF cards to meet high-speed storage and large-capacity expansion needs.
The development board features multiple MIPI-CSI camera interfaces (up to 4 lane, configurable), HDMI 2.0 4K@60fps output, and MIPI-DSI display interfaces, supporting multi-screen independent display and high-frame-rate video capture. Integrated high-speed connectivity including Wi-Fi 6E & Bluetooth 5.3, Gigabit Ethernet, and USB 3.0 provides comprehensive hardware foundations for AI inference, edge computing, and multimedia terminals across all scenarios.
Octa-core CPU + 6TOPS NPU:
The Benchmark for Edge AI Computing Power
The RK3576 octa-core processor (4×A72 + 4×A53) supports multi-task parallel processing and high-performance computing.
The 6 TOPS NPU supports private deployment of large models based on the Transformer architecture (such as the ChatGLM series and Qwen series), compatible with the RKNN/RKLLM toolchain to enhance edge AI development efficiency.
Professional-Grade Multimedia and Visual Processing
Video Encoding and Decoding
Supports 8K@30fps/4K@120fps decoding and 4K@60fps encoding, meeting high-definition video processing needs.
Triple-Screen Heterogeneous Display
Supports multi-channel display output via HDMI, MIPI-DSI, and DP, enabling multi-screen interaction and information dashboards.
Multi-Camera Connectivity
Features 3 MIPI-CSI interfaces, supporting 4K@60fps capture for intelligent vision and NVR systems.
High-Speed Storage with Industrial-Grade Interfaces
Compact Design with Full-Scenario Adaptability
The development board features a compact interface layout, providing a 40-pin expansion port (UART/PWM/I2C/SPI/CAN/GPIO) and supporting 5V/3.3V power output.
Supports OrangePi OS, Ubuntu, Android 14, Debian, and other operating systems, providing comprehensive development resources and community support to help developers get started quickly and customize deeply.
