The Robot Power Scorpion Mini is a small low-cost
high-performance dual channel H-bridge speed controller for small robots,
and other electrical loads. It is designed for ant and beetle weight
combat robots, R2D2 replicas, sumo robots, and other small robots such as
firefighting robots, maze solvers and carpet rovers. The Scorpion Mini is
also suitable to drive pneumatic valves, solenoids, relays and
thermoelectric coolers.
The Scorpion Mini is designed to pack the highest power
handling capability, flexibility of control and usability options into
the smallest package.
Features
- Size: 2.00" x
1.50" x .5"
- Weight: 24.0 grams
- Standard R/C pulse format
- 6.0V to 28V battery
voltage
- 6.5A continuous (8A peak)
current on each channel.
- Fully reversible H-bridge
design. Equal power handling in both directions on both channels.
- Full current limiting and
over temp limiting. This thing is nearly blow proof! Motors and
batteries are protected from dead short conditions.
- Two channels may be
either mixed (throttle/steering) or separately controlled. Ideal for
skid steer vehicles/robots.
- Indicator LED for speed
and direction of motor on each channel
- Status LED status
information and mode indications
- 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.
- Failsafe shuts off motors
if R/C signal is lost
- Calibrate function to
match unit to radio signal range. Settings retained in EEPROM
non-volatile storage.
- Mix Jumper can be cut to
enable separate control of each channel
- Lipo Jumper can be cut to
enable low-voltage cutoff when using Lipo
batteries. This avoids over discharge which can damage batteries of
this type
- FLASH-based
microcontroller with upgradeable software via in-circuit programming
header
- Ceramic oscillator
(crystal) for stable operation at all temperatures
