I'll give it a shot..

Heres the specs on the driver
Standard 5V TTL CMOS Enable, Step and Direction inputs interface with virtually all step and direction controllers including Microchip PIC, Atmel AVR and PC parallel port CNC software.
This state-of-the-art, high power drive is very conservatively rated at 6 amps per phase.
Maximum step rate for this drive is over 200 KHz.
Connecting the Enable input to Ground disables the outputs of the drive so stepper motor shaft could be rotated freely.
High quality screw type terminal blocks with sliding pressure plates (will not fall apart when wire is removed) on all inputs and outputs, make connection to this drive very easy and reliable.
Half or Full step operation is set with an on board jumper.
Stepper motor current is adjustable from 1.5 to over 6 amps via an on board trim pot. This drive does not require any external power resistors to set the stepper motor current.
This drive features automatic stepper motor idle current reduction to 25% of full current. This feature could be defeated with on board jumper so the motor runs at full current all the time.
Drive is mounted on custom designed, heavy yet compact, heat sink for cool and reliable operation.
Drive has dimensions of 3.2" L x 3.0" W x 2.5" H.
Drive is designed to perform, be efficient and last a long time.
