Main features of the Qik 2s9v1

• Connect with 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.

• 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 on the motor supply (not on the logic supply)

• 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.

• 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.

Included Hardware

• 16×1 straight 0.100" male header strip,
• a 12×1 right angle 0.100" male header strip, and two red shorting blocks. This hardware offers several options when it comes to making connections to the qik.

How to use Qik 2s9v1

• wires can be directly soldered to the qik pins themselves.

• the desired header strip can be broken into a 12×1 piece and two 2×1 pieces and soldered into the qik control pins and jumper pins respectively. This allows connections to the qik via custom-made cables that have female headers on them, or the qik can simply be plugged into a breadboard. Using the right angle header allows for a compact profile or for vertical mounting into a breadboard, while using the straight header allows for breadboarding as shown in the picture above.
