1. Sabertooth 2x12 RC User s Guide Input Voltage 6V to 25V 2s to 6s lithium Output current Up to 12A per motor Peak output current Up to 25A per motor Weight 1 50z 43 grams Size 2 35 x 1 85 x 6 DimensionEngineering Sabertooth 2x12 RC is designed for combat robots from 160z to 121b and general purpose robots up to 1001b It controls two motors in mixed or independent modes Its synchronous regenerative drive allows for high efficiency operation and recharges your battery when you slow down or reverse It is internally protected from damage due to overheating and over current Installation Overview Battery connections The positive usually red wire connects to the B terminal and the negative usually black wire connects to the B terminal Using a polarized mating battery connector such as Deans Ultra is recommended to ensure a reliable connection Motor connections Connect Motor 1 to the M1A and M1B terminals and Motor 2 to the M2A and M2B terminals Fwd CH1 connector This connector controls the forward backwards motion of your robot in Mixed mode and Motor 1 in independent mode It is usually connected to the elevator channel on an R C receiver Turn CHz2 connector This connector controls the turning motion of your robot in Mixed mode and Motor 2 in independent mode it is usually connected to the aileron channel on an R C receiver Mounting Sabertooth 2x12 RC mounts with four 4 40 machine screws inc2. ell preventing damage to a lithium battery pack The detected cell count is flashed on the Status 2 LED Switch 3 should be in the UP position when using NiCd NiMH or lead acid batteries Acceleration Ramping Switch 4 in the DOWN position shown turns on acceleration ramping This will cause the Sabertooth to smoothly change speed over an approximately quarter second Switch 4 in the UP position means no acceleration ramp is active Ramping enables smoother control and reduces peak current draw in heavy robots Auto Calibrate Switch 5 in the UP position sets auto calibrate mode In auto calibrate mode the neutral position is read at power up and the end points are automatically detected Switch 5 in the DOWN position shown uses the saved calibration settings The default saved settings are 1500us center 1000us min and 2000us max The saved settings can be changed to accommodate different radios 2 ee Calibrate and Store Switch 6 DOWN and Switch 5 UP puts the controller in Calibrate and Store mode In this mode the first signals sent to the controller sets the stored center point when using saved calibration settings The longest and shortest signals sent to the controller on each channel set the endpoints Turn switch 6 UP before powering down to save the settings Microcontroller Mode Switches 5 and 5 both DOWN shown enables microcontroller mode In this mode timeout is disabled and the controller will run at
3. luded on a 1 5 x 2 hole pattern For best thermal performance it should be mounted with the bottom aluminum heat spreader connected directly to a metal chassis if possible Indicator LEDs The red Error LED will light to indicate overheating or current limit The green Status1 LED will glow dimly when power is applied and brightly when a radio signal is present The green Status2 LED will flash out the detected number of lithium cells when lithium mode is enabled The green Status2 LED and red Error LED will blink simultaneously when a low voltage condition has been detected Options All options are set by using the option switches wee ye Mixing Mode With switch 1 in the UP position the controller is in mixed mode In this mode the signal sent to the FWD channel controls the forward back motion of both motors while the Turn channel controls the difference in speed between the two motors Switch 1 in the DOWN position shown allows control of the motors independently Exponential If switch 2 is in the UP position the controller will be in exponential mode This makes the response less sensitive in the center This is useful to bring very fast robots under control If switch 2 is in the DOWN position shown exponential is disabled and the response is linear Lithium Mode Switch 3 in the DOWN position shown enables lithium mode for use with lithium batteries This will shut the controller down at 3 0 volts per c
4. the last commanded speed until a new command is given using the saved calibration settings This is useful when running from a microcontroller like a Basic Stamp
