Scorpion HX

Dual 6A Ant/Beetle Speed Controller with 12A Weapon Control

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

Scorpion Mini -
Single-Channel Electronic Speed Controller

The Robot Power Scorpion Mini is a small low-cost high-performance single-channel speed controller for 1 lb. (antweight), 3 lb (beetleweight) 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.

The Scorpion Mini is designed to pack the highest power handling capability in the smallest package.

NOTE: You will need to solder your motor and battery leads onto the board, otherwise you can purchase a screw terminal block (sold here) that can be soldered on, which will allow you to connect the wires easily with a small screwdriver. Either way, SOLDERING IS REQUIRED.

Features
• Size: .05” x 1.25” x .4” (without screw terminal)
• Weight: 5.5 grams with servo lead installed
• Standard R/C pulse format
• 4.8V to 18V battery voltage (up to 36V with external 5V supply)
• 2.5A continuous (6A peak) current
• Full current limiting and over temp limiting. This thing is nearly blow proof!
• Drive chip 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.
• Indicator LED for speed and direction of motor
• Receiver battery eliminator circuit (BEC) standard – may be disabled. 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)
• Failsafe shuts off motor if R/C signal is lost
• FLASH-based microcontroller with upgradeable software via in-circuit programming header
• Optional 4 position screw terminal may be soldered to top or bottom of PCB for easy removal of battery and motor wires
