1. 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 [http://www.pololu.com/catalog/

product/708] 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 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 on the power supply

Main Features of the Qik 2s12v10

• Simple bidirectional control of two DC brush motors.

• 6 V to 16 V motor 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.

• Error output to make it easier for the main controller to recover from an 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 error or serial timeout for additional safety.
