The Robot Power Scorpion Nano is a super 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 and other small robots such as firefighting robots, maze solvers, micro sumo and carpet rovers. The Scorpion Nano is also suitable for low-power pneumatic valves, solenoids and relays.

The Scorpion Nano is designed to pack the highest power handling capability, flexibility of control and usability options into one of the smallest dual motor controls available.


  • Size: 0.75" x 0.60" x .15"
  • Weight: 6.0 grams
  • Standard R/C pulse format
  • 3.3V to 16V battery voltage
  • 1.2A continuous (2A 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. 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.
  • 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 3.3V 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
  • Comes with pre-soldered RC and battery/motor wires for easy assembly into your robot
