Manufacturing
3D vision
in a small package
RealSense Depth Module D421 is the first all-in-one module integrating the D4 Vision Processor with the optical module on the same board. The RealSense vision processor D4 does all depth calculations onboard, making this a low power, platform-agnostic device.

Easy to
integrate
Plug-and-play functionality and the integrated single board with the module and the D4 vision processor ensure easy setup and compatibility with popular development frameworks. RealSense Depth Module D421 is supported by the RealSense SDK 2.0 and compatible with a wide range of platforms and operating systems, including Windows, Linux, and Android.
Versatile
vision-based
AI Applications
RealSense 3D Stereo technology is an integral part of any vision-based AI solution. Seeing the world in 3D allows for faster machine learning and lowers the time to deployment for automated solutions. D421 is equipped with 1MP global shutter depth sensors, and advanced depth-sensing algorithms for high-speed depth applications.
Best for
moving robots
and more
Lightweight, low-power, and easy-to-use depth cameras give robots the ability to navigate landscapes, avoid obstacles, and recognize objects, people, and more. With its compact size, ease of use, and high-performance depth-sensing capabilities, this module opens up a world of possibilities for applications ranging from 3D scanning to 3D glasses to toys and fast-moving consumer robots.
