A stepper motor driver is a circuit which take low voltage/current control signals for what the motor should do, and converts them to the high voltage/current needed to send to the motors.

			There are generally two parts which are tightly integrated: a motor controller which converts gcode to motor signals, and a series of motor drivers which convert those signals to the levels needed for the motors. In the RAMPS system, the AM stands for arduino mega which runs a firmware which is the controller. The PS stands for pololu shield which is a few motor drivers connected to the arduino.

			They can definitely manage a 2.5A stepper with microstepping. Since their BOM cost is in the single-digit dollars, I definitely recommend you try them first. Their current control is at 0.25V/A, so you want to set them to 2.5Asqrt(2)/20.25V/A = 0.44V. Remember, for a 2.5A stepper with microstepping, you only need sqrt(2)/2 of its max current in each coil, so 1.77A for a 2.5A stepper. The ones from Pololu are closed source and have slightly worse thermal design, but they should be able to keep up with your steppers too."
