Scorpion Mini Product Information 

  

Finally, the new Scorpion Mini v2.4 is here! This new Mini features enhanced features and more reliable RC processing.

Just wanted to take the time from building to comment how awesome the Scorpions truly are. I reversed input polarity on my omniwheel bot. 2 Scorpion Minis and 1 Banebots ESC. The Banebots is now toasted, while the Scorpions remain functional. Never realized just how robust these things were.

Scorpion Mini

The Robot Power Scorpion Mini is a small low-cost high-performance single channel H-bridge speed controller for small robots, and other electrical loads. It is designed for ant and beetle weight combat robots, sumo robots, and other small robots such as firefighting robots, maze solvers and carpet rovers. The Scorpion Mini has also been used to drive pneumatic valves, solenoids, relays, thermoelectric coolers, and magnetic torque devices.

The Scorpion Mini is designed to pack the highest power handling capability in the smallest package.

Features

  • Size: .625” x 1.6” x .4” (without screw terminal)
  • Weight: 6.0 grams with servo lead installed
  • Standard R/C pulse format
  • New in 2.4 Calibrate function to match unit to radio signal range. Settings retained in EEPROM non-volatile storage.
  • 4.8V to 34V battery voltage (>18V requires an external 5V supply)
  • Fully reversible H-bridge design. Equal power handling in both directions
  • 2.5A continuous, 4A with heatsink, (6A peak) current
  • Full current limiting and over temp limiting. This thing is nearly blow proof!
  • Drive chip mounted on the bottom of the unit for easy attachement of heat sink if desired. Not generally necessary but it will extend the time you can run at above 2.5A.
  • New in 2.4 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
  • New in 2.4 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
  • New in 2.4 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
  • New in 2.4 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.
