The Robot Power Wasp is a small low-cost high-performance
single channel H-bridge speed controller for DC motors, and other electrical
loads. The Wasp is designed for small combat robots, sumo robots, and
other small robots such as firefighting robots, maze solvers and carpet
rovers. The Wasp may also be used to drive pneumatic valves, solenoids,
relays, thermoelectric coolers, and magnetic torque devices that require
bi-directional control.
By making use of advanced autmototive
grade components the Wasp is able to pack robust high power handling
capability in the smallest package.
Features
- Size: .65" x
1.85" x .44"
- Weight: 9.0 grams with
servo lead installed
- Standard R/C pulse format
- Calibrate function to
match unit to radio signal range. Settings retained in EEPROM
non-volatile storage.
- 6.5V to 28V battery
voltage (>20V requires an external 5V supply)
- Fully reversible H-bridge
design. Equal power handling in both directions
- 10A continuous, 30A peak
current
- Full current limiting and
over temp limiting. This thing is nearly blow proof!
- Limit switch inputs to
stop motion in one direction when closed. Motion is allowed in the
other direction.
- Indicator LED for speed
and direction of motor
- 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. (Must be
de-rated for input voltage above 16V)
- Failsafe shuts off motor
if R/C signal is lost
- FLASH-based
microcontroller with upgradeable software via in-circuit programming
header
- Ceramic oscillator (crystal)
for stable operation at all temperatures
- Optional 4 position screw
terminal may be user soldered to top or bottom of PCB for easy
removal of battery and motor wires
- Capable of supporting I2C
or serial command streams. Not supported by stock R/C software but
user may replace the stock code if desired. Contact us if you would
like to discuss custom software for your application.
