Overview:
- the "Easydriver" is an inexpensive component to drive stepper motors of various sizes
- 750mA per phase
- Step modes adjustable (full step, half step, quarter step, eighth step)
- Default step mode eighth-step (if the motor has 200 steps per revolution, the EasyDriver needs 1600 signals).

More details:
For full technical details, see the A3967 datasheet. 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, as well as any other cards you use to power the Easy Driver, to one or more of the GND pins.
M +: This is the power input to 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).
M +: This is the power input to 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. The diagrams below will tell you 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 solid.
Step: This must be a digital signal from 0 V to 5 V (or 0 V to 3.3 V if you have set your Easy Driver this way). Each rising edge of this signal will cause 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 which direction to step (or microstep).
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 which direction to step (or microstep).
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 disconnect the APWR jumper (SJ1), you can use the 5 V pin as a VCC input for the Easy Driver and power it with your own VCC supply.
