Installation: How to download and flash the operating system image to the eMMC or SD card of Orange Pi 3 LTS?
To use Orange Pi 3 LTS, you need to download and flash an operating system image to the eMMC or SD card of the board. The following steps will guide you through this process:
Go to the official website of Orange Pi ( and select the "Download" tab. You will see a list of available operating system images for different models of Orange Pi boards.
Find the image that matches your Orange Pi 3 LTS model and your preferred operating system. For example, if you want to use Android 9.0 on your Orange Pi 3 LTS with 2GB RAM and 8GB eMMC, you can choose the image named "OrangePi_3_LTS_Android9_20210618.img". Click on the "Download" button to download the image file to your computer.
Extract the downloaded image file using a tool such as 7-Zip or WinRAR. You will get a file with the extension ".img". This is the operating system image that you need to flash to your eMMC or SD card.
Insert an eMMC or SD card into your computer using a card reader. Make sure that the card has enough capacity to hold the image file. For example, if the image file is 4GB, you need at least a 4GB eMMC or SD card.
Download and install a tool such as Etcher or Win32 Disk Imager that can flash image files to eMMC or SD cards. Launch the tool and select the image file and the target eMMC or SD card. Click on "Flash" or "Write" to start flashing the image file to the eMMC or SD card.
Wait for the flashing process to complete. It may take several minutes depending on the size of the image file and the speed of your eMMC or SD card. Do not interrupt or eject the eMMC or SD card during this process.
Once the flashing process is done, safely remove the eMMC or SD card from your computer. Insert it into your Orange Pi 3 LTS board. Connect a power supply, a monitor, a keyboard, a mouse, and other peripherals to your board. Turn on your board by pressing the power key. You should see the boot screen of your chosen operating system on your monitor.
Congratulations! You have successfully installed an operating system on your Orange Pi 3 LTS board. You can now explore and enjoy its features and functions.
