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 115.2 kbps 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 16 V; the continuous current per channel is up to 13 A (30 A peak).
