Scorpion XL Speed Controller

Descripción

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 • 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 • 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
