Description of product: Simple High-Power 18v25 driver engine USB 30V/25A - 1381 Pololu

The driver allows to control the DC motor is supplied with the voltage from 5.5 V to 30 V with current consumption up to 25 A. the System of HighPower supports 4 control modes: USB, TTL serial, analog voltage and radio signal RC. The application provides easy way to configure the module.

The manufacturer provides a detailed user manual.

The kit requires a quick soldering basic electronic elements.

The main features of the driver

  • Easy to use controller bidirectional DC motors
  • Power supply: 5.5 V to 30 V (version 18v7, 18v15, 18v25) and to 40 V (24v12, 24v23)
  • From 7A up to 25 A DC, depending on version
  • Four communication protocols:
    • USB direct connect to computer
    • TTL serial interface for connection with the microcontroller
    • The radio signal (RC)
    • Analog input (0 - 3.3 V) - connect potentiometer or joystick
  • Simple setup via USB (Windows 7, Vista, XP,Linux )
  • Detailed information is available in the user manual



For systems using a 24 V supply voltage,we recommend you to use driver 24v12 or 24v23. In the case of drivers 18v17, 18v15 and 18v25 there is a danger that the voltage at some points exceeds the tolerance 24 (e.g., when fully charged battery), which can lead to utrwalę damage to the system.


  • The manual contains connection examples and source codes
  • Adjustable starting speed and the maximum
  • Option protection against accidental starting of the engine
  • Adjustable PWM frequency from 1 kHz to 22 kHz
  • The possibility to switch off at too low voltage
  • The led indicating an error




Example of connection controller.


Drivers series HighPower can communicate via three interfaces:

The USB port of the computer

  • Communication with PC via virtual COM port
  • Code examples in C#, Visual Basic, .NET, C++
  • Additional safety functions (control CRC, timeout)
  • Automatic detection of data transmission speed from 1200 bps to 500 kbps)


Remote Control - device modeling

  • Frequencies from 10 to 333 Hz
  • Adjustable parameters for the signal RC
  • Two channels
  • The ability to power the receiver from the BEC (the BEC jumper)


Analog Interface

  • Resolution: 12 bits
  • Voltage range: 0 to 3.3 V
  • Two analogue channels
