Processor (1)

The SoC powers ROCK 5B is Rockchip RK3588. The main system CPU is a Quad-core ARM Cortex-A76 MPCore processor and quad-core ARM Cortex-A55 MPCore processor, both are high-performance, low-power and cached application processor. Embedded ARM Mali-G610 MP4 3D GPU makes RK3588 completely compatible with OpenGLES 1.1, 2.0, and 3.2, OpenCL up to 2.2 and Vulkan1.2. Special 2D hardware engine with MMU will maximize display performance and provide very smoothly operation. The build-in NPU supports INT4/INT8/INT16/FP16 hybrid operation and computing power is up to 6TOPs. In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.

RAM (2)

The ram for ROCK 5B is LPDDR 4x, two 32bits LPDDR 4x chips make 64bits, data frequency is up to 4224Mhz. ROCK 5B offers 4GB, 8GB and 16GB ram size options.

USB Power (3)

The Radxa ROCK 5 Model B is designed to be an ARM desktop Single Board Computer with low power consumption. It supports the following power input:

  • USB PD2.0 power adapter which support 12V/15V/20V with 2A current or higher output
  • Power adapter with fixed 9V to 20V DC voltage and USB C plug
  • 5V PoE power from the GPIO PIN 2 & 4

eMMC (13)

Socket on Board Interface Feature

The high performance eMMC module is the best choice as the system storage for ROCK 5B. The eMMC module with 8GB/16GB/32GB/64GB/128GB is available.

The eMMC Socket pin specification shows below.

GND 16 19 GND
GND 17 18 GND

TF (14)

The TF card can be used as a system storage or an external storage.

When it's used as a system storage, you had better choose the ones with storage space larger than 8GB.

When it's used as an external storage, you can choose the ones with storage space up to 128GB.

When the TF card is inserted into the TF card slot , the device will be automatically recognized by the system.

The TF card interface pin specification shows below.
