It combines four high-performance Cortex-A72 cores clocked at up to 2.2 GHz and four energy-efficient Cortex-A53 cores up to 2.0 GHz for the perfect balance of speed and power consumption.

The built-in NPU neural processing module with a performance of up to 6 TOPS opens up limitless possibilities for artificial intelligence and machine learning tasks. This is an ideal solution for robotics, complex computing, smart video surveillance and the creation of multimedia systems.

• Rockchip RK3576 octa-core processor with up to 2.2 GHz frequency and 6 TOPS NPU for AI tasks.

• 8 GB LPDDR5 RAM for handling the largest data and applications.

• Flexible storage options: microSD slot, eMMC 5.1 and UFS 2.0 module slots, optional NVMe SSD via HAT .

• Advanced multimedia capabilities with 8K video decoding and support for two independent displays.

• Industrial version with operating temperature range from -40 to +85 °C for use in all conditions.

Operating principle and computing capabilities

Radxa ROCK 4D is a complete single board computer measuring just 87x58mm. It easily integrates into any systems. The Rockchip RK3576 processor with big.LITTLE architecture dynamically distributes the load between powerful and energy-efficient cores. It delivers peak performance when you need it and energy savings when you're not working. The built-in NPU with a performance of 6 TOPS supports INT4/INT8/INT16/BF16/TF32 formats, allowing you to perform neural network inference locally without going to the cloud.

The Arm Mali-G52 MC3 graphics subsystem supports modern APIs, including OpenGL ES 3.2, OpenCL 2.0 and Vulkan 1.2. It provides excellent interface handling and rendering. The hardware video decoder is capable of processing 8K@30fps video in H.265, VP9, ​​AV1 formats, and the encoder is capable of processing up to 4K@60fps. This makes the board ideal for multimedia systems, digital kiosks and professional video capture.

Technical characteristics and interfaces

Explore the rich connectivity options of the Radxa ROCK 4D. LPDDR5 memory is available in 8GB version. For storage, there is a microSD slot, a connector for eMMC 5.1 or UFS 2.0 modules (only one is used at a time). It is also possible to connect an NVMe SSD via an optional PCIe HAT.

Video outputs include HDMI 2.1 supporting up to 4K@120fps and 4-lane MIPI DSI for connecting a second display . The cameras are provided with one 4-line and one 2-line MIPI CSI interface. Network capabilities are represented by a Gigabit Ethernet port with a PoE option, Wi-Fi 6 and Bluetooth 5.4 modules with two antenna connectors.

The USB kit includes two USB 3.0 Type-A ports (one with OTG support) and two USB 2.0 Type-A ports. A 40-pin Raspberry Pi compatible GPIO header is available for expansion. The board supports UART, SPI, I2C, PWM, CAN and other interfaces. Power is provided via USB Type-C (5V) or via GPIO.

Areas of application and operation

Radxa ROCK 4D is available in commercial (0...+70°C) and industrial (-40...+85°C) versions. This expands its application from home laboratories to outdoor equipment and transportation systems. The board will be an excellent basis for a powerful robot controller or personal cloud server. There are also environmental monitoring or high-performance media player systems.

Supported operating systems include Debian Linux, Android 14, Yocto and Buildroot. The board attracts a huge community of developers and enthusiasts who are ready to share experiences and solutions.
