Qik Dual Serial Motor Controller

Product Description

Description: The Qik Dual Serial Motor Controller is Pololu?s second-generation dual serial motor
controller. 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. It provides ultrasonic, 8-bit PWM
speed control via an advanced, two-way serial protocol that features
automatic baud rate detection up to 38.4 kbps and optional CRC
error checking. Two status LEDs give visual feedback about the serial
connection and any encountered error conditions, making debugging easy,
and a demo mode allows easy verification of proper operation.

This controller also supports
daisy-chaining the Qik to other Qiks and Pololu serial motor and servo
controllers, allowing the control of an almost unlimited number of
motors and servos with a single serial line.

It can also be configured to use 15.7 kHz, 7.8 kHz, or 3.9 kHz PWM frequencies.

Features:

• Simple bidirectional control of two DC brush motors
• 4.5 V to 13.5 V motor supply range
• 1 A maximum continuous current per motor (3 A peak)
• 2.7 V to 5.5 V logic supply range
• Logic-level, non-inverted, two-way serial control for easy connection to microcontrollers or robot controllers
• Optional automatic baud rate detection up to 38400bps
  
• Two on-board indicator LEDs (status/heartbeat and serial error indicator) for debugging and feedback
• Serial error output to make it easier for the main controller to recover from a serial error condition
• Jumper-enabled demo mode allowing initial testing without any programming
• Optional CRC error detection eliminates serial errors caused by noise or software faults
• Optional motor shutdown on serial error or timeout for additional safety
• Supports
  daisy-chaining the qik to other qiks and Pololu serial motor and servo
  controllers, allowing the control of an almost unlimited number of
  motors and servos with a single serial line
