Sabertooth Dual 32A Motor Driver

This is far above hobby grade. Using this to power a heavy robot with relatively powerful motors and it has worked excellent. I'm using a Raspberry Pi to send signals to the motor driver. There are many ways to interface with the Sabertooth but Serial port seems the most convenient method, and Python has great support for it. The only issue that came up during a stress test was the chip on the Sabertooth got bogged down and took a long time to sift through the command queue, but that is because I was sending motor speed modification commands at about 45 times per second. So the chip had to interpret the plain text command sent over serial and then translate that motor frequency way faster than it should have. I guess a buffer was getting full causing the queue problem. There are other interface methods that would get around this problem by not requiring the chip to translate serial commands, and they are all listed on the instructions included with item.

Ok- this is a well thought out, reasonably priced and compact little powerhouse. Has dozens of programming options not listed in the description to make it even more useful. As an example, you can custom adjust the response curve of the motors (symmetric or assymmetrically) to the degree of motion of the input signal, and the one I found most useful: you can program a limit on the current to the motors, preventing expensive burn-out in case of motor stall.Kudos to whoever designed this thing!

This thing is great. I put a on off power switch inline from battery power to the sabertooth. (and connected + and - from the batter) Removed the electromagnetic brakes from the 2 motors on my chair (to simplify) connected the chair motors to m1 + and m1 - (motor 1) and m2+ and m2- (motor 2) Connected power from the sabertooth 5v out to my receiver. Ran the signal wire from my first channel to s1 from the receiver (only the one wire is needed) Same for the second channel, to s2 on the sabertooth. (the + and - from the receiver aren't required because the power to the motors are going coming from the sabertooth, not from the receiver) Then I connected to the sabertooth with usb (leaving the battery connection in the off position) Set up my parameters for RC-- Sabertooth mixing the channels for me, and made sure that the brakes were not enabled (since I removed them) Wrote my changes to the sabertooth and voila'! Oh. I did have to turn it on and link to my radio. Amazingly, it worked first try!

used this for a powerwheels application to add soft start and control speed, overkill for my application but fun to play withwould consider Roboclaw instead for next project, their product is similar but online documentation and manual is superior.I will say Dimension's customer service is excellent, just documentation needs improvement

dimension engineering really did it this time. you have the option of connecting via USB to configure the device. you have more inputs on this one which allows you to tie in sensors to control your device. I installed the motor controller on a jazzy wheelchair, plug and play and the wheel chair took off. no special skills required. motor controller does not get hot, I believe this version can handle more amperage. this is truly an amazing product

What a great product from a great manufacturer. I just fried the controller by connecting the wires wrong(reverse polarity).I contacted Dimension Engineering and they were so helpful. Although it is my own fault that I fried the controller they are replacing the item.I read really good reviews about dimension engineering but I wasn't expecting them to be so good.I don't really leave reviews but after being pleasantly shocked how awesome this company was, I think they deserve the highest rating ever possible.I definitely recommend this item or anything from this company!

Product failed and may have burned out my motors. It caused the motors to behave erratically before it stopped functioning entirely. I triple checked my wiring and don’t see any error on my end. This motor controller is completely dead after less than two minutes of run time.

In just a couple hours I had this thing running a pair of motors with incredible precision using a cheap $4 Arduino Nano clone (with a bunch of potentiometers, sensors, and buttons hanging off of it) and the Dimension-supplied Arduino packet-serial libraries. Beautifully easy, incredibly flexible. Really, I don't need 75% of the capabilities of this unit (analog control inputs, R/C "pulse" input, completely customizable this and that, braking control, etc, etc!) But for what I needed it to do - run a pair of 24V 250W motors (and larger motors eventually) with all the precision I need, and supreme ease of programming... wow. Perfect. Hopefully it lasts a good long time. I'll definitely be adding forced ventilation to the enclosure to be sure I don't cook this thing in the summer.
