|1. Choose a free SD card you would like to install emteria.OS onto. Attention: Please use a card of at least speed class 10 or higher (UHS), since the read/write speed of the SD card will heavily influence the system speed. Best results are achieved by using cards of type A1 (see this public discussion). Some cards are known to not work correctly with the Raspberry Pi; this is a hardware issue we don’t control. Please check this comprehensive list for your specific SD card.|
|2. Use the emteria GUI installer for your operating system in order to flash your SD card. Warning: all data on this sd card will be lost!|
|3. When the installer finishes, take your micro SD card out of your computer, insert it into your device and power it on. You should see a short text boot sequence followed by the emteria logo animation.|
All standard HDMI screens should be supported. Please see the section below for more information about the supported resolutions. The majority of USB-based touch controllers should also work out-of-the-box. Following screens have been successfully tested by us with emteria.OS 0.5.x:
|52Pi 5″ touchscreen: The 800×480 capacitive HDMI touchscreen with USB controller for multi-touch.|
|Raspberry Pi 7″ touchscreen: The official Raspberry Pi 7″ touch screen display with 10 finger capacitive touch.|
|Waveshare 4.3″ touchscreen: A capacitive DSI screen.|
|Waveshare 5″ touchscreen: A capacitive DSI screen.|
|Waveshare 7″ touchscreen: A capacitive HDMI screen with a USB touch controller.|
|Waveshare 10.1″ touchscreen: A capacitive HDMI screen with a USB touch controller.|
The audio jack is used as the default audio out. If it doesn’t work in your setup, or if you wish to change the default behaviour, please refer to HDMI_FORCE_EDID_AUDIO and HDMI_IGNORE_EDID_AUDIO options as specified by the official documentation. The emteria.OS also has built-in support for USB speaker and USB microphone without additional configuration.
Built-in support for the Official CSI camera module without additional configuration.
Built-in support for ODROID’s USB GPS Module without additional configuration.
Built-in support for NXP’s USB NFC Dongle without additional configuration.

Additional applications can be installed in the same way as on standard Android devices (ADB, Download, F-Droid):
- Copy your application to a USB drive and connect it to your Pi. Open the File Manager application, navigate to the USB drive and install the application from there.
- Since Raspberry Pi has no USB OTG, “ADB over Ethernet” should be used instead of standard ADB. Please activate it first in the settings (Settings -> Emteria -> Enable ADB over Ethernet). An example can be found here. New applications can be installed directly from your PC using
- You can use the preinstalled application market to install new applications. One example of using F-Droid can be found here.

emteria.OS only can use WiFi online, if you synchronize the time with the internet. Because the Raspberry Pi 3 does not have a real-time clock you need to synchronize the time manually each time you start your RP3 after a while.
To do so, follow these simple steps:
- Access the settings menu
- Scroll down to “System” (depending on which version you use, you might have to look for “general”)
- Scroll down until you see the “Date and Time” option
- Set the date yourself via Set date
- Select the date format of your choice
- Set the time yourself via Set time
- Select the time of your choice
- Leave the “Date and Time” option
