I hit the link to have a look at the specs, but it comes up with a "page not found error". It's possible it could work with an EZ-B, but a look at a datasheet would be good to be sure.

Yes it will work . It will work in either RS-232 mode (such as the sc-32 controller works), or PWM mode (which simply works as a modified servo movement panel)

Theoretically yes, it has two operating modes, one of which makes it look like a continuous rotation servo, so that "should" be plug and play with the EZ-B. I say "should" only because the Parallax HB25 controller also should have worked and it took some extra scripting for anyone to get it to work, and the sabertooth controllers also have an R/C mode that should work but doesn't. That being said, it looks from a quick look at the getting started guide that you can adjust the pwm to match the microcontroller, so that should resolve any potential issues. Not all features are supported in R/C mode, the most important one probably bring the ability to use encoders for position control.

It also has a serial mode that supports all features that may be accessible with scripting and either send serial commands on any digital port, or if it is two-way, through one of the uarts. That would take more research. It is rs-232 and the EZ-B is TTL. In some cases they are interchangeable, in others, not.

And DJ just made my post irrelevant while I was typing it.

alan, your post was far more useful and detailed

That is very good news

Steve G I will try and give you the PDF Datasheet link Vex Motor Controller I hope this works

DJ and Alan thanks for the quick responses. I am still waiting for my EZB 4 so I will read up on scripting and the Sabertooth/HB25 controllers.

Any usefull links or information to help spearhead my progress would be very much appreciated.

I am a Newbie so theres a good chance I will be asking more questions down the line

This is a really cool community

For HB25, just search the forums. It just uses the modified servo movement panel, but you need to run an initialization script to send it a command (sorry, I don't remember what the command is right now, but a search for HB25 or HB-25 should find it).

Sabertooth has built in control in ARC, but there are also a lot of threads about scripting the commands in a custom Movement Panel to give more control (like ramping hte speed up and down, which the Jaguar appears to provide natively even in R/C mode).

Looks like a good unit, and I see why you want to get one now since they are selling off the backstock before a replacement unit comes out, and $79 for a 40 amp controller is a really good price (although I didn't look to see if that is 40 amp per channel, or just 20 amp per channel, in which case the price is just good, not great....)

Here is more on the difference between TTL and RS-232 and why you may need some additional circuitry to make it work in serial mode connected to an EZ-B UART. https://www.sparkfun.com/tutorials/215
