What is the smallest / cheapest computer that can pull images from three RealSense D435 cameras?

[idata]

Hey all,

I'm looking for the cheapest computer that meets these requirements:

• Can connect three D435 RealSense cameras
• Capture a single frame from all three cameras
• Send those frames over the network

Any recommendations?

Thanks.

The discussion link below about connecting multiple D415s to an Up Board single-board computer via a USB hub may be useful to you.

The Intel store has a bundle deal of a D435 camera and Up Board. So you could save a bit of money by getting one bundle and two individual D435s.

If you already have three D435s, the Up Board can be bought from the store on its own.

For some reasons all the links to the Aaeon board from the Intel forums are broken.

The board itself is not that cheap, it's $200. I know it's currently bundled with the camera but I need something that will be available for a few years at least, and something that is cheap when it's not a limited-time bundle, as I will be buying many of these over the next 2-3 years.

The links are working okay for me.

Raspberry Pi have just launched the Raspberry Pi 3 Model A+ for $25.

For around $35, the older B+ model has 1 GB of memory instead of the A+'s 512 GB.

The 400 Series cameras work with Pi, though in a limited capability USB 2.0 mode.

I need something that can pull the full resolutionfor the depth data (even if it's very low FPS)

The budget may limit your available options. Aside from Up Board and Jetson TX2, the next most frequently occurring choice of single board computer on the Librealsense forums is Odroid XU4.

Intel Compute Stick is another option, a mini PC on a stick that can connect to a display via HDMI.
