Yes, that is a 5v regulator. I saw a post from DJ recently that they have actually changed the component and the regulator is now built in and it only requires 3 wires instead of 4 (ping and receive use the same signal wire, like the Parallax sensor). Photo on the shopping page still shows the original.

Excellent, thank you.

You got it! Less wires. Easier to use. And less ports needed on the ezb. Progress rules!

does the new device give you more accurate results or usages?

Accuracy is limited by natural world physics. Sound waves don't always bounce back from all materials. Also some angles redirect the sound and it never comes back. It's the best it can be

What do you mean by "usages"?

I just starting using the 4 wired one that came with my Roli order that was delivered this past Wed., and only "played" with it today. Seems to only be only showing 255, so need more time to experiment with settings window, etc. to understand what usages you have already covered in tutorials, etc. Thx

If it returns only 255, the ECHO and PING wires may be connected in reverse. You can either swap the wires on the ez-b or change the assignments in the config.

I can say that the latest 3 wire version is easier to use because the ECHO and PING are on the same wire. That's about the extent of the improvement.

Can the present settings window be uses with the 3 wire one, like parallax ping? I presently have pings on my S3 and Sparki, both read well and "block" type coding has them navigating ok.
