SR305 vs SR300

  The SR305 is essentially an SR300 Depth Module camera circuit board in a new casing that makes it easier to mount the camera.  It should otherwise behave the same as the old SR300 cased USB camera.

  SR305s purchased from Intel's online RealSense store can be shipped directly to Poland.

  thank you very much for your quick reply!

  Could you help me with these doubts abt SR300?

  - missing protection against dust and physical shocks - is it completely volatile in comparison to SR305?

  - does the board need any cooling that normally the case provides?

  - does the board have the normal connectors (USB and power) or do you need special cables?

  I'm guessing that you are referring to the caseless SR300 Depth Module board?  If so ...

  -  When handling a Module Board, you have to be careful not to flex it with your hands, or it may need re-calibrating afterward because of movement in the sensors. 

  The SR300 Depth Module does have some covering for the board, though it is probably assumed that the board is going to be enclosed in some kind of protective casing supplied by the system integrator.  In general, hard physical knocks like severe vibration, hard knocks and drops on the floor should be avoided if possible, even with the cased USB cameras.   If you expect the camera to experience strong vibration during use then design vibration damping into its mount points if possible.

  

  If you have an industrial need for dust water water proofing, it will be up to you to provide it with a custom casing, as the board is not IP66 rated (the new D435e from FRAMOS is).

  -  In regard to power, you have two options: a 10 pin connector suited to system integrators (so they can connect the board to their particular hardware platform), and the ability to add USB port components onto that connector so that a USB cable can be attached to it.

  In previous years, it used to be very hard to obtain the 'IPEX' USB connector housing parts detailed in the SR300 data sheet.  Fortunately since then, a USB adaptor board has become available:

  Please ensure that you refer to the new June 2019 'Edition 2' of the joint SR300 and SR305 data sheet instead of the old edition 1 from 2016 to ensure that you have the latest technical information.

  https://dev.intelrealsense.com/docs/intel-realsense-sr300-datasheet 

  Pages 36 to 38 contain guidance on designing a thermal solution to extract heat.  The data sheet says that you can minimize the need for a passive heat spreader if your product uses a metal chassis, otherwise you may need to include a heat spreader component if the chassis is plastic.

  An official CAD model file for the RealSense SR305 is now available if you should require it.
