Sabertooth Serial

How To Add This Control To Your Project

  1. Load the most recent release of EZ-Builder.
  2. Press the Project tab from the top menu bar of EZ-Builder.
  3. Press Add Control from the button ribbon bar of EZ-Builder.
  4. Choose the Hbridge category tab.
  5. Press the Sabertooth Serial icon to add the control to your project.
This control supports the Sabertooth HBridge Motor Driver as a movement panel with variable speed in Simplified Serial mode.

The Sabertooth Electronic Motor Controllers are high power. They come in many versions that range from small to large robotics. The EZ-Builder software supports the Simplified Serial Mode at multiple baud rates (suggested 9600) on the configured port.

Dip Switches

Consult the Datasheet of your Sabertooth product for dip switch settings. The suggested Sabertooth setting is Simplified Serial at 9600 Baud. Lower baud rates can be used if interference or poor functioning is experienced.

Baud Rate

It is important to understand how the ez-b v4 and sabertooth communicate. This is done over a serial connection. Serial may seem simple enough in wiring, but the baud speed is a very important attribute that prevents the communication from working. The BAUD SPEED of the serial connection is the absolute most important property and must match between the EZ-B v4 and Sabertooth. If the speed is not understood between the sabertooth and ez-b controller, it won't work. Ensure both the EZ-B and Sabertooth are using the same baud rate.

Consult the manual for your Sabertooth model for the baud rate settings. The suggested baudrate is 9600, which much match the setting in the config menu of this control. Press the GEAR icon on the sabertooth control to view settings. Lower baud rates can be used if interference or poor functioning is experienced.


The EZ-B connects to the GND and Signal to the Sabertooth. The Signal from the EZ-B connects to S1 on the Sabertooth, which is used for Simplified Serial mode. The Sabertooth will get its power from the Power terminals that you connect to the battery. The GND must be shared between the ezb and Sabertooth, even if the battery supply of each is different.

Product Details

Sabertooth allows you to control two motors. You can build many different robots of increasing complexity for years to come with a Sabertooth. Sabertooth has independent and speed+direction operating modes, making it the ideal driver for differential drive (tank style) robots and more.

The operating mode is set with the onboard DIP switches so there are no jumpers to lose or complicated programming sequences. Sabertooth features screw terminal connectors - making it possible for you to build a robot without having to solder.

Sabertooth is the first synchronous regenerative motor driver in its class. The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse. Sabertooth also allows you to make very fast stops and reverses - giving your robot a quick and nimble edge.

Sabertooth has a built in 5V BEC that can provide power to a microcontroller or R/C receiver. It also features a lithium cutoff mode allowing Sabertooth to operate safely with lithium ion and lithium polymer battery packs - the highest energy density batteries available.
