Dual H-Bridge Motor Controller substitute?

Hey,

I’m building a tank bot and the original plans called for the “Dual H-Bridge Motor Controller” that I see Lynxmotion doesn’t sell it anymore.

What would be an alternative to this controller? I’m new to bot building and electronics and want to make sure I get the right item.

Thanks to all.

The Dual H-Bridge product used TTL speed and direction signals where the enable lines were used for speed PWM. We no longer have a motor controller that works in this way. Here is the motor controller page.

Thanks for the info.

So for the interaction that I had between my OOPic-R microcontroller and the twin Tamiya DC gearmotors I am using, do you have an idea of which motor controller(s) would give me roughly the same functionality? With two motors, would I need two channels and hence, two of the single channel controllers?

Sorry for the basic level questions.

Thanks

The OOPic can generate hobby servo pulses, so I recommend the Sabertooth 2 x 5 RC. Simple and easy.

If the motors you are using are 4.5 to 6 volts and similar in size to the servo motor, you might be able to use the motor control out of a servo like below and attach it to your motor.

Just out of curiosity, what is the functional/practical difference between the two controllers:

Sabertooth 2X5 R/C Regenerative Dual Channel Motor Controller
DE-10

and

Sabertooth 2X5 Regenerative Dual Channel Motor Controller
DE-09

They are the same price and look to be pretty similar in specs. Why/where would I use one over the other?

Thanks again for all the help.

The DE-09 allows you to control through serial control as well as a string of them each addressed differently on a single serial interface. Use this control if you will need several attached to a single serial connection (packetized serial) or want to use simplified serial signals from a microcontroller. Since it also supports R/C PWM control then it is the best product for experimenting.

The DE-10 is strictly servo PWM control but may include the wiring harness for the difference in capability. Use this unit if you know you will be using R/C control or in fact will be connecting to a standard R/C receiver.

I’ve used the DE-05 for a while in simplified serial. It works very reliably and is quite smooth and quiet on a number of motors. I really like the serial communication to interface to microcontrollers.
