Rockchip RK3399 SBC is one of the most powerful SoC platforms. The board is a good choice for developers and makers as it has a high performance, low power consumption, and low cost. The latest version of these chips is rk3588 from rockchip, which is now being used in most powerful SBCs. These SBCs are much more efficient and high-performing but still not widespread as the RK3566.

The RK3566 is the successor to the popular RK3066 SoC (also manufactured by Rockchip). It has a big board, supports 4K Ultra HD video playback and recording, HDR 4K video playback and recording, 4k@60fps at 8-bit per pixel format, supports H.265/HEVC Main Profile 10-bit encode/decode for all codecs with 1Gbps bandwidth Max bandwidth (10Mbps) on all ports including Gigabit Ethernet port.

The main differences between the Rockchip RK3399 and RK3566 are that the former uses the Allwinner A80 SoC while the latter uses Allwinner A83T (the same chip used in MediaTek mt6592). Both boards have 2GB RAM with a DDR memory interface. However, only one has 1GB RAM or less (either 512MB or 256MB).

Board Interface

The Rockchip RK3566 SBC board has four different interfaces:

  • HDMI output
  • USB 2.0 host interface (2x)
  • Ethernet RJ45 connector (1x)
  • TF card slot for storage expansion by using microSD cards or other memory cards

You can also use this slot to install an operating system on your computer, so you don’t have to change out the whole motherboard if you want another OS installed on it later on down the road!


The RK3566 has a total of five ports. It includes:

  • USB 2.0 port
  • SD card slot
  • HDMI port (HDMI 2)
  • Ethernet port
  • TF Card Slot

The board has two USB host ports, one on each side of it. These are used for connecting peripherals such as keyboards or mice to the board’s internal USB bus, which is used for communication with external devices such as storage devices and printers.

This board is also compatible with the headphone and microphone jack that allow the user to enjoy their gaming or shoe time without any interference.

Hardware Decoding

The RK3566 is designed with multiple hardware decoding features that support high-resolute and ultra-fast video and audio applications. A few of these programs are;

  • CPU: Rockchip RK3566 ARM Cortex-A55 Quad Core up to 1.8 GHz (Max)
  • GPU: G52MC2
  • DDR3: 2000MB (Max)
  • eMMC: NAND Flash 32GB(Max), 16GB(Max)
  • SD: SD card reader x1 slot on the board, support both SDHC/SDXC cards
  • HDMI port supporting HDCP 2.2 & CEC protocol; supports up to 1920×1080@60Hz@30bit color depth with up to
  • 60Hz refresh rate on the analog TV output mode
  • USB 3.0 port x2 in total, one of them located at the bottom side of PCB, which supports USB OTG function, and another located at the backside, which supports USB 2.0 super speed data transfer rate up to 5Gbps at full duplex configuration.

Raspberry Pi B+ does not support this feature due to its limited resources. However, Rockchip RK3566 board comes with an internal USB 3.0 controller, which provides enough bandwidth for most applications.


Rockchip is a company that makes chips and other hardware for mobile phones, tablets, laptops, and other devices. Their RK3566 SBC board has been used in many applications, including surveillance cameras and wireless routers. The board includes two ethernet ports that allow connection to networks using either WiFi or Ethernet cable connections.
