Second generation two-channel driver for DC motors Qik 2s9v1 , which allows to control the speed and direction of rotation of the engine, using a simple serial interfacethat allows easy connection of the driver to the controller (e.g. Arduino), computer with a serial port (requires external Converter RS-232 levels) or network adapter, USB Serial. The supply voltage for the motors is from 4.5 V to 13.5 V, maximum current up to 1 amp. Nutrition logic: 2.7 V to 5.5 V.

Provides ultrasonic, 8-bit PWM speed control via bilateral Protocol of the serial interface, which provides automatic detection of data transmission speed to 38.4 kbps, and additional error checking CRC. Two status LEDs provide visual feedback about the serial connection and any of the occurred errors, make debugging easier, and a demo mode allows easy to check the correctness of the action.


The product is compatible with Arduino

The manufacturer provides a library for Arduino.

Differences relative to previous versions and competitive products:

  • PWM high frequency (ultrasonic), eliminates the noise while the engine is
  • Fast communication Protocol
  • Visible LEDs and a demo mode
  • Protection against reverse direction of the engine
