รายละเอียดสินค้า: Dual Serial Motor Controller

This powerful motor controller allows variable speed and direction control of two large, brushed DC motors using a simple serial interface and provides several advanced features, such as motor acceleration control and configurable current limiting. Automatic baud detection up to 115.2 kbps and inputs for both RS-232 and TTL serial make it easy to add motors to your microcontroller- or computer-based project. The operating voltage range is 6 to 16 V; the continuous current per channel is up to 13 A (30 A peak).

 

Overview

The qik 2s12v10 adds a comprehensive yet easy-to-use, high-power option to Pololu’s line of motor controllers. The compact board—it’s almost the same size as the dual VNH2SP30 carrier board by itself—allows any microcontroller or computer with a serial port to drive two brushed DC motors with full direction and speed control, providing up to 13 A (continuous) per motor channel without a heat sink and tolerating peaks as high as 30 A.

 

The improvements over competing products include:

  •     - high-frequency PWM to eliminate switching-induced motor shaft hum or whine
  •     - a robust, high-speed communication protocol with user-configurable error condition response
  •     - visible LEDs and a demo mode to help troubleshoot problematic installations
  •     - reverse power protection

 

For a lower-power version of this controller, please consider the qik 2s9v1. For similar devices that support additional features and control interfaces, please consider the TReX motor controller and high-power motor controller with feedback, and for a robot controller based on the qik’s drivers, please consider the Orangutan X2 robot controller, which connects the VNH2SP30s to a user-programmable ATmega644 AVR microcontroller.

 

Main Features of the Qik 2s12v10

  •     - Simple bidirectional control of two DC brush motors.
  •     - 6 V to 16 V operating supply range.
  •     - 13 A maximum continuous current per motor (30 A peak).
  •     - Logic-level, non-inverted, two-way serial control for easy connection to microcontrollers or robot controllers.
  •     - RS-232-level, one-way serial control for easy connection to a PC serial port.
  •     - Optional automatic baud rate detection from 1200 bps to 115.2 kbps.
  •     - Seven on-board indicator LEDs (power, status/heartbeat, error indicator, and motor indicators) for debugging and feedback.
  •     - Advanced features include configurable acceleration, motor current feedback, and current limiting.
  •     - Error output to make it easier for the main controller to recover from an error condition.
  •     - Optional motor shutdown on error or serial timeout for additional safety.
  •     - Jumper-enabled demo mode allowing initial testing without any programming.
  •     - Optional CRC error detection eliminates serial errors caused by noise or software faults.
