Pololu Qik 2s12v10 Dual Serial Motor Controller
This powerful motor controller allows variable speed and direction control of two large, brushed
DC motors using a simple serial interface and provides several advanced features, such as motor acceleration control and configurable
current limiting. Automatic baud detection up to 115.2kbps and inputs for both
RS-232 and TTL serial make it easy to add motors to your microcontroller- or computer-based project.
The operating voltage range is 6 to 16V; the continuous current per channel is up to 13A (30A peak).
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 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 13A
(continuous) per motor channel without a heat sink and tolerating peaks as high as 30A.
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
For a lower-power version of this controller, please consider the qik 2s9v1.
For similar devices that support additional features and control interfaces, please consider the Simple High-Power Motor Controllers,
TReX motor controller, and jrk 12v12 motor controller with feedback.
For a robot controller based on the qik’s drivers,
please consider the Orangutan X2 robot controller,
which connects the VNH2SP30s to a user-programmable ATmega1284 AVR microcontroller.
