This is a 1110-POLOLU Qik 2s9v1 Dual Serial Motor Controller.
This small, inexpensive motor controller allows variable speed and direction control of two small, brushed DC motors using a simple serial interface, making it easy to add motors to your microcontroller- or computer-based project. The motor supply voltage range is 4.5 to 13.5 V; the continuous current per channel is up to 1 A (3 A peak). The logic supply can be as low as 2.7 V, allowing operation with modern microcontrollers running at 3.3 V.
