Chapter 1 GR3399 Development Board Introduction
1.1 Brief Introduction
GR3399 dev board bases on Rockchip RK3399 (64bit) chip platform, which is designed
by Shenzhen Graperain Technology Co., Ltd..
GR3399 dev board consists of GR3399 SOM and carrier board.
GR3399 SOM is based on Rockchip RK3399, 64 bit 6-core, work-station-level processor.
It’s Dual-core Cortex-A72 + Quad-core Cortex-A53. The frequency is up to 2.0GHz. The
new kernel is almost 100% performance up than A15/A17/A57.
Integrated with ARM Mali-T860 MP4 graphics processor, supports OpenGL
ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, Directx11, AFBC ( ARM Frame Buffer
Compression ). Such powerful GPU supports H.265HEVC and VP9, H.265 encode and
4K HDR. And it can be applied to computer vision, learning machine, 4K 3D etc..
Interfaces: Dual MIPI-CSI, dual ISP, PCIe, USB3.0, USB2.0, TypeC etc.
GR3399 development board designed almost all the functions of the CPU, especially in
data communication and expansion. Peripherals on board including: 4G LTE, TypeC,
USB3.0, USB2.0, Gigabit Ethernet, dual-wifi, bluetooth, audio/video input/output, sensors,
display port, communication port, cameras etc..
It supports Android7.1, Linux and Debian. Source code are open.
Applications: high-definition display with advertising machine, vending machines, teaching
terminals, automatic identification, robotics, security monitoring, financial POS, vehicle
control terminals, VR, etc.. With the dev board to test, it will accelerate product
development time.
GR3399 dev board features:
Size: 186mm*116mm, can be used in final product.
Powerful functions, rich interfaces, wide applications.
Supports Android7.1, Linux, Debian. Source code open, accelerate develop time.
Stable and reliable board.
