Buying a controller and H-bridge instead of building?

I have already built my AMC and H-bridge but as most of us already know it's a bit expensive.
Is it possible to buy an Arduino Uno and a Double BTS7960B 43A Motor Driver High-power module as you can find in ebay?
The total cost is about $40, could this work?
Would be alot easier for new user to buy and not to build... :?

Wow did you see the shipping costs? $100 US to ship it to me. Doesn't look like it would be to hard to reverse engineer that PCB.

No need to reverse engineer it if you would like to make your own, just look through the datasheet http://www.robotpower.com/downloads/BTS ... -12-07.pdf

From what I have read, the h-bridge is easy, the AMC controller is where the problem is, problem components, pcb issues, firmware problem.
The Arduino looks good, but unless you are a programmer (of which I am NOT) then the code needs to be sorted by someone else.
The K8055 is buggy, so issues there.
So what is left?
The JRK? And nothing else?
:

im part way through code for ard to run a
hbridge, implementing pid is the hard part.

how about poloulo jrk 12v12....very good and easy to get working

I must admit I have no knowledge about the finer details of electronics. So maybe a dumb question:

Could I use the motor outputs of two jrk’s as the S1 & S2 input signal for a Sabertooth 2X60? (VIN on the jrk's would be 5V rather than 6-16V of course.)
I’m aware that this might not be the most cost effective solution, but I have the jrk’s already.
And I wouldn't have to bother about the programming and would have 3x the power of the original jrk.

Thats an idea I had, but was not sure how to work it. Maybe you have got it. If there is an h-bridge that accepts a 6-16v signal source, then in theory, yes it should work. As for cost effective, sometimes paying more for an easier solution is better. Consider your time and efforts in setting up the AMC or other home made boards, when if your idea works, you have got something done faster and less headache.

I think you would release the magic black smoke if you connect it that way...because on the motor terminal it switches from + to - al time...and you have grounded one..

+1

The bridges aren't synchronised, imagine what will happen if lower fet of other bridge is low and on the other driving the same load is high... :

didnt think of that, it would go BOOM!!!
Still if there is an H-bridge that accepts a 6-16v source, it could potentially work, but maybe one jrk feeding into an h-bridge. And not two. If there was a way to pull the signal out of the board that tells the motor driver what to do, you'd be on to something.
Besides that, maybe Pololu should look at developing a more gruntier jrk.
Then again, if you are planning to run more than 40 amps at 12 volts, the motors had want to be TOUGH! My motors spike between 32-38 Amps as it is. They are on the edge already.

It would be great ,if sirnoname i whilling to make a plugin in the near future
for the black jaguar controller,24 volt 40 amp continious
fore info and price search with black jaguar @ digi key
he is good for all low voltage sytems

Well, this is only true if you define in the Profiler under USO Datapack with axisinformation the Jrk command Set Target High Resolution (i.e. any number between 192 and 221 [commonly used with x-sim]).
In order to keep the polarity on the jrk's motor output constant (e.g. A = –, B = +) one has to use the command Set Target Low Resolution Forward (224) instead.

There come the tarp motors into play again. They pull up to 400 amps @ 12V according to the performance charts at the bottom.

:?? confused…
All I know is that the two channels of the Sabertooth can be controlled independently: Independent mode - two separate analog signals control two separate motors independently. Can you explain what you mean. As I said, I have no knowledge about the finer details of electronics.

Why not use one jrk feeding a signal to one sabertooth? After all, are you planning to use the sabertooth as the main motor driver, and the jrk as the signal for it?
