Dagu Rover 5 tracked chassis. What motor driver is needed

Hi
Can anybody tell me what sort of motor driver I’ll need for this. I’m using an mbed microcontroller which runs at 3.3v. Should I use a H-bridge device ? Will I need two, one for each motor ?

You need a dual motor controller capable of providing ~1.5A at ~7.2V. We offer many, many such DC motor controllers. Can you check if the I/O also operate at 3.3V instead of 5V?
