Sabertooth 2x10 RC Users Guide

Sabertooth 2x5 RC User’s Guide:

Input Voltage: 6V to 18V (2s to 4s lithium)

    Output current: Up to 5A per motor Peak output current: Up to 10A per motor

    Weight: .6oz/18 grams Size: 1.8” x 1.6” x .5”

Sabertooth 2x5 RC is designed for combat robots from 150g to 3lb, and general-purpose

    robots up to 30lb. 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/CH2 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. Flip connector This connector is used to reverse the steering if your robot gets flipped upside down. It can connect to either a 0V-

    5V signal for automatic flip correction or an R/C channel (usually channel 5 or 6) for radio-controlled flip correction. Mounting: Sabertooth 2x5 RC mounts with two 2-56 machine screws (included) on a 1.5” x 1.25” 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 blue Status LED will glow dimly when power is applied, and brightly when a radio signal is present. In Lithium mode, the blue Status LED will flash out the number of lithium cells detected.

    Options: All options are set by using the option switches.

Mixing mode: With switch 1 in the UP position, the controller is in mixed mode. Switch 1 in the DOWN

    position (as shown) turns mixing mode off. Note that Flip (Switch 4) only affects Motor 2 if mixing mode is

    off.

     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 (as shown) exponential is disabled and the response is linear.

     Lithium Mode: Switch 3 in the DOWN position (as shown) enables Lithium mode, for use with Lithium

    batteries. This will shut the controller down at 3.0 volts per cell, preventing damage to a Lithium battery

    pack. The detected cell count is flashed on the blue status LED. Switch 3 should be in the UP position when

     using NiCd, NiMH or lead-acid batteries.

    Flip control: Switch 4 in the UP position sets flip to R/C mode. When R/C mode is set, the bot’s steering

    will be reversed if the R/C pulse is 1500us or longer. Switch 4 in the DOWN position (as shown) sets flip to digital input mode. If you are not using the Flip channel (if your bot is not invertible) set switch 4 to DOWN.

     Auto-Calibrate: Switch 5 in the UP sets auto-calibrate mode. In auto-calibrate mode the neutral position is

    read at power-up and the endpoints are automatically detected. This maximizes your useful stick travel, and

    allows use with pistol-grip transmitters with 70/30 throttles. Switch 5 in the DOWN position always uses

    1000us for full reverse, 1500us for stop and 2000us for full forward. Timeout: Switch 6 in the UP position enables timeout. If no signal is received for 1 second, the controller

    turns the motors off. This prevents your bot from driving away if you get interference. If Switch 6 is in the

    DOWN position, timeout is disabled and the controller will run at the last commanded speed until a new

    command is given. This is useful when running from a microcontroller like a Basic Stamp.
