The Robot Power Scorpion HX is a flexible high-performance 3 channel speed controller for 1 lb. (ant weight), 3 lb (beetle weigth) and larger robots. It is designed for ant and beetle weight combat robots, sumo robots, and other small robots such as firefighting robots, maze solvers and carpet rovers. A unique feature of the Scorpion is the integrated 3rd Auxiliary/Weapon channel which may be used for a weapon or sumo vacuum system. This along with the built-in mixing functions allows an all-in-one solution for small robots previously unavailable at any price.

Features
The Scorpion HX contains the following features:
* Size: 1.6” x 1.6” x .5”
* Weight: 22 grams with servo leads installed
* Four R/C input leads for
* Left and Right Drive
* Auxiliary Weapon - proportional - forward only
* Flip Control
* 4.8V to 22V battery voltage (up to 36V with some component changes)
* 6A peak, 2.5A continuous (4.5A with heatsink) current on Left and Right drive channels. May be combined into a single 12A continuous forward/reverse channel. This is a real 2.5A rating i.e. you can put 2.5A through the drive channels the better part of a full match with higher peaks for a few seconds.
* 12A continuous, 35A peak current on the Weapon/AUX channel. This can be used to drive a forward-only motor such as a spinning weapon or sumo vacuum system.
* Full current-limiting and over-temp limiting on drive and Aux channels. This thing is nearly blow proof!
* Drive chips mounted on the bottom of the board for easy attachement of heat sink if desired. Not generally necessary but it will extend the time you can run at above 2.5A per drive channel.
* Flip input reverses motor direction when the robot is inverted. May be operated via an R/C channel or via a mechanical (gravity) or optical etc. switch.
* 4 indicator LEDs for Left/Right speed and direction and Aux speed. A status LED shows the R/C signal status and other information
* Left/Right channel mixing is the default – may be disabled
* Receiver battery eliminator circuit (BEC) standard – may be disabled if desired. This can provide up to 100 mA of current at 5V to the RC receiver and other attached electronic circuits. (Must be de-rated for input voltage above 12V)
* Safe start for Aux channel disables the robot at power up until the Aux channel is in the 'off' position.
* Failsafe shuts off motors and weapon if R/C signal is lost
* FLASH-based microcontroller with upgradeable software via in-circuit programming header
