This is an step-by-step guide to flash Ubo App image to a MicroSD card. You can run this image on Ubo Pod or bare Raspberry Pi 4/5.

• A MicroSD card (at least 8GB)
• A computer with Linux, macOS, or Windows
• A USB-to-SD card adapter or a built-in card reader

Download the Ubo App image from the Ubo App Release Page

Under the release section, there are two images to download; One is lite image which does not include Desktop Environment and the other is full image which includes Desktop Environment.

Please note that the full image is split into two parts (a and b) that you need to download and combine them before flashing to the MicroSD card using the following command:

cat [[filename]]_* > [[filename]]

If you start with Lite image, you can still install Desktop Environment later by going to Menu > Settings > System > Desktop on the GUI.

Insert the MicroSD card into the USB-to-MicroSD card adapter or the built-in card reader
