 ====== DC Motor Controllers ======
-To drive motors using a microprocessor requires converting low-power digital logic into high current voltage signals to actual motors.  Usually some kind of intermediate chip or circuit is required to do that, especially if the motor should turn in both directions.  There are three chips that we've worked with.  They are: half h-bridges, full h-bridges, and RC-PPM servomotor controllers (from the [http://www.dimensionengineering.com/products/sabertooth2x5|2-5

 To be written.
+===== Motor Controllers/Drivers =====
+These implement a lot of the circuit components associated to H-Bridges and abstract away the details so that you can focus on just supplying the two most important signals, direction and speed.  Examples include the Sabertooth series (from the[[http://www.dimensionengineering.com/products/sabertooth2x5|2x5]] to the [[http://www.dimensionengineering.com/products/sabertooth2x60|2x60]]), as well as the possibly newer line [[http://www.dimensionengineering.com/products/syren10}SyRen XX]] of regenerative motor drivers.
 ===== RC-PPM Servomotor Controllers =====
-The most popular, according to our experience, of RC-PPM servomotor controllers are the Sabertooth models.
+The most popular, according to our experience, of RC-PPM servomotor controllers are the Sabertooth models  (e.g., the [[http://www.dimensionengineering.com/products/sabertooth2x5rc|2-5]] and the [[http://www.dimensionengineering.com/products/sabertooth2x12rc|2-12]] RC models. They take as input RC servomotor PPM signals and output the right kind of PWM signal needed to drive a motor at a turn rate based on the given PPM signal.
