Sabertooth Dual 12A 6V-24V Regenerative Motor Driver

I purchased it for Lynxmotion A4WD1 V2 chassis. Aluminum plate was twisted from factory. When I screwed it to flat bottom firmly one of radiators fеll off. I had to use thermal paste for computer CPU heathink and glued on perimeter by CA glue. Still there till now. Originally I played with robot controlled by Arduino. Then robot wasn't in use for one and half year. I cleaned up dust, removed Arduino Mega and put RC receiver to play outside as rover with FPV gear. Internal BEC is not enough for receiver with one normal size servo (camera pan mount). FPV equipment had power from separate Lipo. Power drops, robot stucks and servo goes to end of range. I disconnected servo and everything was fine. I had about 30 minutes of fun with 2-3 brakes. Yesterday I added separate 3A BEC to power receiver with servo. Obviously with two signal wires from receiver to motor driver I should connect ground line. Several minutes everything was Ok, then robot stuck just on flat floor without any forse on it like obstacles or something. In several seconds magic smoke came from motor driver despite the statement that it has all kind of protections. I meashured voltage and current when robot runs. Maximum (full throttle) was 1.8 amperes for four motors. Nothing for this motor driver. By specifications 120 RPM motors have 5A stall current. So, I expected some room (2A per channel) for safety but alas. Robotshop, is this covered by warranty or I should throw it in the trash? ----------------------------------------------------------------------------------------------------------------------------------------- Comment from RobotShop: Yes, this product is under warranty for a period of one year.

As advertised, powerful software but easy to use. Plenty of power for your motors.

First you can tell that a Lot of effort & knowledge went into the making of this board. It is made to take all of the guess work out of having to think about the controller for Robots. It not only allows for wasy setup but, the biard can actually recharge your batteries! Setup takes less than a couple of minutes, and it readily hands between 2-4 servos. It is almost plug and play. And it is so GREAT that I will buy another one. Don't waste your time buying a different Board- Because THIS IS WHAT YOU NEED!!! And it has a Great Price. GREAT WORK- Dimension Engineering!

Sabertooth work well,quite and no problem on start and stop.

This is a great motor driver, very flexible. I'm using it with my Wild Thumper 6WD chassis. Build quality is great, documentation is great and easy to understand. RobotShop is also great to work with, knowledgeable and helpful folks!
