The complete technical details can be found in the A3967 data sheet. The Easy Driver is just a breakout board for this driver chip, so the datasheet is your best source of information on how everything works.

GND: The Easy Driver has three GND (ground) pins. They are all connected together inside the board. Connect the negative side of your power supply and any other cards you use to power the Easy Driver to one or more of the GND pins.
M +: This is the power input of the Easy Driver. Connect this to the positive cable. This should be a clean power supply of 6 V to 30 V, 2 A (or more).

A and B: (four pins) These are the motor connections. See the diagrams below for how to connect them. A and B are the two coils of the motor and can exchange the two wires for a specific coil (only the direction of the motor is reversed). Make sure this connection to the motor is tight.

Step: This must be a digital signal from 0V to 5V (or 0V to 3.3V if you have set your Easy Driver this way). Each rising edge of this signal causes a step (or microstep) to be executed.
DIR (direction): This must be a digital signal from 0 V to 5 V (or 0 V to 3.3 V if you have set up your Easy Driver this way). The level when this signal (high / low) is sampled on each rising edge of STEP to determine in which direction the step (or microstep) should be executed.

MS1 / MS2: These digital inputs control the microstep mode. Possible settings are (MS1 / MS2): Full step (0,0), half step (1,0), 1/4 step (0,1) and 1/8 step (1,1: default).
RST (Reset): This input signal resets the internal translator and disables all output drivers.
SLP (Sleep): This normally high input signal minimizes power consumption by disabling the internal circuits and output drivers when held low.
ENABLE: This normally low input signal disables all outputs when pulled high.
PFD: This one is complicated - see the datasheet for more information.
5 V: This is an OUTPUT pin that supplies either 5 V (default) or 3.3 V from the voltage regulator at a low amount of current (e.g. 50 mA - depending on the input voltage) to power a circuit that you may need to power. If you remove the APWR jumper (SJ1), you can use the 5 V pin as a VCC input for the Easy Driver and supply it with your own VCC supply.

Customer reviews for "A3967 Stepper motor driver - "Easydriver" / 750mA per phase"

Klasse Produkt!

Habe hier ne Menge von den easydrivern bestellt, da verschiedene Projekte umzusetzen waren eben mit Schrittmotoren.
Nach Adjusten des Stromes mittels Poti haben alle auf Anhieb funktioniert. Lediglich sind bei 2 Schrittmotoren, die ich bestellte, die Verdrahtung falsch gewesen bzw. stimmte das Datenblatt nicht mit den Gegebenheiten überein. Dies hatte aber nichts mit den easydriver Modulen zutun.

Bin sehr zufrieden und für diesen Preis einfach unschlagbar. Versand ging fix, ich werde wieder hier bestellen :)
