The Robot Power Scorpion XXL is a two-channel motor controller that is both flexible and high-performance for small to medium mobile robots such as firefighting robots, sumo, robotic combat, theater props, inspection, EOD and other applications. It can be used for robots as heavy as 90 pounds or more as long as the motor current limits are respected. The Scorpion XXL is suitable for other applications as well including lights, hydraulic valves and other static non-robot uses. The Scorpion XXL contains the following features:
20A continuous current (45A peak) each on Left and Right channels. 25A continuous current with fan cooling
6.0V to 28V battery voltage
Full current limiting and over temp limiting. Nearly blow proof!
Size: 3.27" x 2.27" x .5"
Weight: 1.8 oz (52g) with servo leads but without enclosure
Two R/C input leads and one pin header for: ·Steering/Throttle or Left/Right Control - fully reversible H-bridge channels ·Flip Control - reverses controls if robot is flipped over (optional)
2 Indicator LEDs for Left/Right speed and direction. A status LED shows the R/C signal status and other information
Left/Right channel mixing or separate channel control option
Brake/Coast at zero speed option
Linear/Exponential steering response option
Lipo battery cutoff option
Switching style 5V regulator eliminates battery voltage worries and provides increased current on the 5V rail for the newer 2.4GHz radio receivers. Works without jumpers from 6V to 28V
Receiver battery eliminator circuit (BEC) standard - may be disabled. This can provide up to 200 mA of current at 5V to the RC receiver and other attached electronic circuits.
Failsafe shuts off motors if R/C signal is lost
Calibration function to match Scorpion to your radio or other signal source - settings stored in EEPROM
FLASH-based microcontroller with upgradeable software via in-circuit programming header
Remote power switch connections to turn unit off without breaking the main power connection
