The Polulu Qik 2s9v1 Dual Serial Motor Controller 1 A is a second generation dual serial motor controller from Polulu. The compact module allows any microcontroller or computer with a serial port (external RS-232 level converter required) to easily drive two small Brushed DC motors with full direction and speed control.

    The improvement over the older generation and competing products includes:
  • High frequency PWM to eliminate switching induced humming and howling of motor shaft
  • A robust, high-speed communication protocol with user-configurable error state response
  • visible LEDs and demo mode to help with troubleshooting installations
  • Rücc power protection on motor supply (not on logic circuit supply)

    Main features:
  • Simple bidirectional control of two Brushed DC motors; see User Manual for more information.
  • >motor power supply range: 4.5 to 13.5 V
  • >Maximum continuous current per motor: 1 A (peak value at 3 A)
  • Range of the logic circuit supply: 2.7 to 5.5 V
  • Logic level, non-inverse, two-way serial controller for easy connection to microcontroller or robot controller
  • Optional detection of the automatic baud rate
  • Two on-board indicator LEDs (status/heartbeat and serial error indicator) for debugging and feedback
  • Serial error output to make it easier to remove the main controller from a serial error state
  • Jumper enabled demo mode that allows initial testing without any programming
  • Optional CRC error detection eliminates serial errors attempted by Lärm or software errors
  • Optional motor shutdown in case of serial error or time error for additional safety
  • supports daisy-chaining with other Qik motor controllers, Polulu serial motors and servo controllers to control an almost unlimited number of motors and servos with a single serial line

  • Motor canals: 2
  • Motor supply voltage: 4.5 to 13.5 V
  • Continuous output current per channel: 1 A
  • Peak value of output current per channel: 3 A
  • Automatic baud rate detection range: 1,200 to 38,400 bps
  • Fixed baud rate: 38,400 bps
  • Mögliche PWM frequencies: 3.9 kHz, 7.8 kHz, 15.7 kHz, 31.5 kHz
  • Logic circuit supply voltage: 2.7 to 5.5 V
  • Protection of the Rückwäd voltage: yes (but only for motor supply)
  • Motor driver: TB6612FNG
