2. Setup Guide
This section outlines the steps required to set up your Orange Pi 4 Pro for initial use.
2.1 Power Supply
The Orange Pi 4 Pro requires a 5V/3A power supply connected via the Type-C power port. Ensure you use a stable and compatible power adapter to prevent operational issues.
2.2 Operating System Installation
The Orange Pi 4 Pro supports various operating systems, including Android, Debian, Ubuntu, and OpenHarmony. You will need to prepare an operating system image and flash it onto a compatible storage medium.
- Choose an OS: Select your preferred operating system image from the official Orange Pi website or community resources.
- Prepare Storage: Insert a MicroSD card (Class 10 or higher recommended) or an M.2 M-Key 2280 PCIe NVMe SSD into the respective slot on the board. The board also supports eMMC/UFS storage.
- Flash Image: Use a disk imaging tool (e.g., Etcher, Win32 Disk Imager) on a separate computer to write the OS image to your chosen storage medium.
- Insert Storage: Once the image is flashed, insert the MicroSD card or M.2 SSD into the Orange Pi 4 Pro.
2.3 Initial Connections
Before powering on, connect the necessary peripherals:
- Display: Connect a monitor via the HDMI port.
- Input Devices: Connect a keyboard and mouse to the USB 2.0 or USB 3.0 ports.
- Network: For a wired connection, connect an Ethernet cable to the Gigabit Ethernet port.

3. Operating Instructions
After completing the setup, you can power on and begin using your Orange Pi 4 Pro.
3.1 Powering On
Connect the 5V/3A Type-C power adapter. The board should automatically power on and begin booting the operating system from the installed storage medium. Observe the LED indicators for boot status.
3.2 Software Environment
Once the operating system has booted, you can interact with it using the connected display, keyboard, and mouse. Refer to the specific operating system documentation for detailed usage instructions.
3.3 Network Connectivity
- Wi-Fi: Configure Wi-Fi settings through the operating system's network manager. The board supports Wi-Fi 6 for high-speed wireless connections.
- Bluetooth: Enable and pair Bluetooth devices via the OS settings. Bluetooth 5.4 provides enhanced connectivity for peripherals.
- Ethernet: If an Ethernet cable is connected, the board should automatically establish a wired network connection. PoE support allows power and data transmission over a single cable, simplifying deployment.
3.4 GPIO Usage
The 40-pin GPIO header provides extensive expansion capabilities for connecting sensors, actuators, and other custom hardware. Refer to the pinout diagram and relevant software libraries for programming GPIO functions.
