Scorpion
XL -
Dual-Channel Electronic Speed Controller
The
Robot Power Scorpion XL is a perfect solution for those robots
in the 1 to 15 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 |
