# Intel® RealSense™ D400 cameras with Raspberry Pi
|
||
|
|
|
||
|
|
This document describes how to use the Intel RealSense D400 cameras on Raspberry PI 3 Model B (which offers only USB2 interface).
|
||
|
|
|
||
|
|
> **Note:** Camera capabilities are severely reduced when connected to USB2 port due to lack of bandwidth.<br />USB2 interface over D400 cameras is supported from FW 5.08.14.0 and on. Later firmware updates add more functionality, such as streaming reduced RGB video and additional Depth resolutions

|
## Installation Instructions
|
||
|
|
1. Install [Ubuntu MATE](https://ubuntu-mate.org/) on your [Raspberry PI 3](https://www.raspberrypi.org/products/raspberry-pi-3-model-b/).
|
||
|
|
|
||
|
|
2. Clone and compile the latest [Intel® RealSense™ SDK 2.0](https://github.com/IntelRealSense/librealsense/releases/latest) by following the instructions under [Linux Installation](https://github.com/IntelRealSense/librealsense/blob/development/doc/installation.md).
|
||
|
|
In the section [Prerequisites](https://github.com/IntelRealSense/librealsense/blob/development/doc/installation.md##prerequisites), proceed with the steps till (not including) the kernel patches instructions.
|
||
|
|
|
||
|
|
> **Note**: In some cases the RAM capacity is not sufficient to compile the SDK, so if the compilation process crashes or exits with an error-code try to create a [swap file](https://www.howtoforge.com/ubuntu-swap-file) and then recompile the SDK.
|
||
|
|
|
||
|
|
3. [Activate](https://ubuntu-mate.community/t/tutorial-activate-opengl-driver-for-ubuntu-mate-16-04/7094) the OpenGL driver.
|
||
|
|
4. Plug the D400 camera and play with RealSense SDK [examples](https://github.com/IntelRealSense/librealsense/tree/master/examples)/[tools](https://github.com/IntelRealSense/librealsense/tree/master/tools).
|
||
|
|
|
||
|
|
## Expected Output
|
||
|
|
1. Streaming Depth data with 480x270 resolution and 30 FPS using the [Intel RealSense Viewer](https://github.com/IntelRealSense/librealsense/tree/master/tools/realsense-viewer).
