Robot MarketPlace - Scorpion XL Speed Controller

The Robot Power Scorpion XL is a perfect solution for those robots in the 1 to 12 pound classes. It may be used on robots up to 30 pounds or more, as long as the motor current limits are respected. By using the latest automotive-rated power chips the Scorpion XL is able to offer features, power handling and load protection unprecedented in any controller of this size.

The built-in drive and mixing functions allow an all-in-one solution for small robots previously unavailable at any price.
    • Exponential Steering response option (helps with fine control)
    • Left/Right Mix (default - one input acts as steering and one as throttle)
    • Mixed Mirror Left (left mixed output sent to both output channels)
    • Mixed Mirror Right
    • Left/Right independent (Tank)
    • Mirror (both outputs mirror a single input)

Features
• Size: 2.7” x 1.6” x .5”
• Weight: 28 grams with servo leads and screw terminals installed
• Three R/C input leads for
     - Left and Right Drive - fully reversible H-bridge channels
    - Flip Control - reverses controls if robot is flipped over (optional)
    - Serial I/O - Flip input doubles as TTL serial I/O port
• 4.8V to 28V battery voltage
• 12.5A continuous current (45A peak) on each Left and Right drive channels. May be combined into a single 25A continuous forward/reverse channel. This is a real 12.5A rating i.e. you can put 12.5A through the output channels for several minutes with higher peaks for a few seconds
• Full current limiting and over temp limiting. This thing is nearly blow proof!
• Surface mount drive chips mounted on the bottom of the board for reliability and to reduce the size of the unit
• 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
• 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 is the default – many mixing modes are available set by jumpers
• Receiver battery eliminator circuit (BEC) standard – may be disabled.
• 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
• Hardware support for I2C/SPI command interfaces
• Hardware support for analog current sensing
• Hardware support for dual-channel quadrature encoders
• Analog voltage feedback inputs built in

Scorpion XL

Great speed controller as usual from Scorpion however only really good for 3 pounders and up and a three pounder is really pushing it sipmly because of the shear size of this controller it's rather large considering it doesn't even have and aux channel, but it does it's job for pushy bots.

manual?????

Good speed controller so far, but I got to give a lower rating on the account that you really can't find a manual for this speed controller.

Very easy to use

This ESC is super simple to use and very reliable as long as you protect it from metal particles, which will kill the CPU. The BEC isn't much good at higher voltages, but for small bots running under 18V, I highly recommend the Scorpion XL
