01. Overview of RK3399
Rockchip Microelectronics Co., Ltd. ("Rockchip", stock code: 603893) was established in 2001, headquartered in Fuzhou, with branches/subsidiaries in Shenzhen, Shanghai, Beijing, Hangzhou and Hong Kong, focusing on integrated circuit design It has developed into a leading Internet of Things (IoT) and artificial intelligence Internet of Things (AIoT) processor chip company.
Rockchip has a R&D team specializing in system-level chips, analog circuit chip design and algorithm research, and has rich experience and technology in processor and digital-analog hybrid chip design, multimedia processing, image algorithms, and system software development. reserve. In addition to various types of processor chips, Rockchip's main products also include power management chips, digital-analog hybrid chips, optoelectronic products and development board products.
Rockchip is market-oriented, with technological innovation as the core, and is committed to providing customers with multi-level, multi-platform, multi-scenario professional solutions, empowering multiple fields such as consumer electronics, intelligent hardware, machine vision, and industrial applications.
rk3399 is a high-performance, low-power "Chinese chip" developed by local chip manufacturer Rockchip. In April 2016, rk3399 debuted at Electronics Fair in Hong Kong. The chip uses six-core large LITTLE processors: including quad-core Cortex-A53 and dual-core Cortex-A72, the main frequency can reach 2.0GHz. The chip is compatible with 3G and 4G network communication, with rich interface resources and excellent overall performance, such as USB3.0, MIPI dual camera and other equipment interfaces. There are also many options in the use of the operating system. Users can choose Android/Linux/Debain as the operating system, or choose light office development environments such as Phoenix and Flint OS. Commonly used software is compatible. In 2017, it was officially announced that the rk3399 Linux system was open source.
The display interface is rich. It can also display dual screens at the same time or dual screens with different displays according to the needs. In terms of video, it supports dual MIPI, HDMI, EDP, DP and many other mainstream display output ports.
2. Diversification of network channels. Dual-band wireless network reception (2.4GHz/5GHz), Gigabit Ethernet port, Bluetooth communication 4.1. In addition, there is a Mini PCle port connected to the development board, which can expand 3G and 4G communication.
3. The peripheral interface is complete. USB2.0/3.0HOST, independent PCIE interface. Conventional serial port debugging, 42Pin GPIO interface is convenient for developers to debug and use.
4. Strong operating system compatibility. Linux, Ubuntu, Debain, Android and other open source operating systems, users can choose the appropriate firmware for programming.
