Installing the Operating System to a MicroSD Card

Download the System Image​

Go to the Downloads Summary page to download the corresponding operating system image archive. After downloading, extract the archive to get the *.img file needed for system installation.

tip

The downloaded system image is a compressed file that needs to be extracted before it can be written to the SD card using imaging software.

Hardware Connection​

Insert the MicroSD card into a card reader, then connect the card reader to your PC's USB port.

Image Flashing Tool​

We recommend using Etcher, an open-source image flashing tool developed by Balena, Radxa's partner. This software is user-friendly, powerful, and supports Windows, Linux, and macOS.

Using Etcher​

Download the software for your operating system from the official website: balenaEtcher

On the download page, select the appropriate platform to download the Etcher software.

tip

For Windows and Linux, simply run the downloaded executable—no installation required!
