Specifications Top

The HB-25 module from Parallax is high-current solution for controlling large DC motors. It is compatible with any microcontroller that can generate a servo compatible pulses, allowing a DC Motor to be controlled similar to a continuous rotation servo. Unlike the servo, the HB-25 does not require refreshing, meaning a single pulse can maintain the output which reduces the load on the microcontroller.

  • Motor Rating: DC motors up to ½ HP
  • Pulse Input: 1.0ms Full Reverse, 1.5ms Neutral (off), 2.0ms Full Forward
  • Pulse Refresh Rate: Single Pulse Operation
  • Modes: Single/Dual Motor Control(control HB-25s using a single IO line)
  • Protection Circuits: Over Voltage, Over Current, Over Heating
  • Fault Reset: Automatic
  • Cooling: Forced Air - Ball Bearing Fan
