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.
