Power interface
The development board provides a USB Type C interface (interface 1) as a power supply interface. You need to use a power adapter that supports 5V/5A to power the development board. After connecting the power adapter to the development board, the green power indicator lights up, indicating that the development board is powered normally. After version 3.1.0, the orange status indicator flashes, indicating that the system is running normally.
Note: Please do not use the computer USB interface to power the development board, otherwise the development board will be abnormally powered off and repeatedly restarted due to insufficient power supply. ! ! ! ! ! !
Debug serial port
The development board provides a debug serial port (interface 4) to realize serial port login and debugging functions. The parameters of the computer serial port tool are as follows:
- Baud rate: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow Control: None
When connecting the serial port, you need to connect the development board interface 4 to the PC through a Micro-USB cable.
Usually, when users use this interface for the first time, they need to install the CH340 driver on the computer. Users can search for the CH340 serial port driver keyword to download and install it.
Wired network port
The development board provides a Gigabit Ethernet interface (interface 6), supports 1000BASE-T and 100BASE-T standards, and uses static IP mode by default. The IP address is 192.168.127.10. If you need to confirm the IP address of the development board, you can log in to the device through the serial port and use the ifconfig command to view the configuration of the eth0 network port.
In addition, this interface supports PoE (Power over Ethernet) function, which can transmit data and power through the network cable at the same time without an additional power cable, making the installation of the device easier and more flexible.
HDMI display interface
The development board provides an HDMI (port 10) display interface, which supports up to 1080P resolution. The development board outputs the Ubuntu system desktop on the monitor through the HDMI interface (the Ubuntu Server version displays the logo icon). In addition, the HDMI interface also supports real-time display of cameras and network streaming images.

Micro SD interface
The development board provides a Micro SD memory card interface (interface 13). It is recommended to use a memory card with at least 16GB capacity to meet the installation requirements of the Ubuntu operating system and related function packages.
Note: Hot-swappable TF memory card is prohibited during the use of the development board, otherwise it will cause system operation abnormalities and even damage the memory card file system.
Wi-Fi antenna interface
The wireless network of the development board supports both onboard and external antenna configurations. Under normal circumstances, the onboard antenna can meet the usage requirements. When the development board is installed with a metal shell, it is necessary to connect the external antenna to (the antenna interface next to interface 12) to enhance the signal strength.

40PIN interface
RDK X5 development board provides 40PIN interface, and IO signal adopts 3.3 V level design.
Precautions
RDK X5 is suitable for laboratory or engineering environment. Please read the following precautions before starting operation:
Do not hot-swap the screen interface, CSI interface and expansion board under any circumstances.
Before unpacking and installing the development board, please take necessary anti-static measures to avoid electrostatic discharge (ESD) damage to the development board hardware.
- When holding the development board, please hold the edge of the development board and do not touch the exposed metal parts on the development board to avoid static electricity from damaging the components of the development board.
- Please place the development board on a dry surface to ensure that it is away from heat sources, electromagnetic interference sources and radiation sources, and electromagnetic radiation sensitive equipment (such as medical equipment).
