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
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.
