Este controlador de motor pequeño, de bajo costo permite velocidad variable y control de dirección de dos motores pequeños DC utilizando una sencilla interfaz en serie, por lo que es fácil de poner los motores a su microcontrolador o proyecto basado en computadora.
El rango de tensión de alimentación del motor es de 4,5 a 13.5A; la corriente continua por canal es de hasta 1A (pico de 3A). El suministro de la lógica puede ser tan bajo como 2,7V, lo que permite la operación con los microcontroladores modernos funcionando a 3,3 V.

The qik 2s9v1 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) or USB-to-serial adapter 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.
The improvements over the previous generation and competing products include:
For a more advanced, higher-power version of this controller, please consider the qik 2s12v10. For a simpler carrier of the qik’s motor driver, please consider the TB6612FNG dual motor driver carrier, and for a robot controller based on the qik’s driver, please consider the Baby Orangutan and Orangutan SV-328 robot controllers and 3pi robot, which connect the TB6612 to a user-programmable AVR microcontroller.
November 27, 2013 update: We have changed this product by replacing the large, silver electrolytic capacitor with a much smaller ceramic capacitor. This lowers the profile of the board but does not affect functionality at all. The main product picture shows this new version; the rest of the pictures on this product page still show the previous version with the tall electrolytic capacitor.

The qik ships with a 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.
For the most compact installation, wires can be directly soldered to the qik pins themselves. For less permanent connections, the 16×1 straight header strip can be broken into a 12×1 piece and two 2×1 pieces. The 2×1 pieces can optionally be soldered into the jumper pins, and the 12×1 header strip of your choice can be soldered into the qik control pins. 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; using the straight header allows for breadboarding as shown in the picture above.
We have written a basic Arduino library for the qik dual serial motor controllers that makes it simple to interface these controllers with an Arduino. The library handles the details of serial communication with the qik, allowing two brushed DC motors to be controlled easily.
