Product description: Qik 2s9v1 two channel motor controller 13.5 V / 1 A - Pololu 1110
Second generation of Qik2s9v1dual channelDC motordriver allows you tocontrol speedanddirection of rotation ofa motor using a simpleserial interface, enabling simple connection of the driver to a microcontroller (e.g. Arduino), computer with serial port (externalRS-232 level converterrequired) or USB - Serial adapter. Supply voltage for the motors rangesfrom 4.5 V to 13.5 V, maximum currentup to 1 A. Power supply for the logic part is:2.7 V to 5.5V.
It provides ultrasonic 8-bit PWM speed control via a bidirectional serial protocol that offers automatic baud rate detection up to 38.4 kbps and optional CRC error checking. Two statusLEDsprovide visual feedback on the serial connection and any errors encountered for easy debugging, and a demonstration mode allows easy verification of proper operation.
Product compatible with Arduino
The manufacturer provides alibrary for Arduino.
Differences from previous version and competing products:
- High frequency PWM (ultrasonic), eliminates the noise coming out of the motor
- Fast communication protocol
- Visible LEDs and demonstration mode
- Protection against reverse motor power supply
Main features
- Bidirectional control of two DC motors
- Motor supply: 4.5 V to 13.5 V
- Maximum continuous current: 1 A (3 A momentary)
- Logic power supply: 2.7 V to 5.5 V
- Optional automatic baudrate range detection
- Two status LEDs
- Serial error output
- Demo mode - with jumpers allows initial testing without program
- Optional CRC error detection, caused by noise or software errors
- Optional motor shutdown in case of serial error or timeout
- Supports module linking, allowing multiple motors and servos to be controlled over a single serial line
- Comprehensive user guide
