A logic low input on this pin puts the A4988 Stepper Motor driver in sleep mode. The sleep pin can be used to minimize power consumption when the motor is not in use. Here we also need to mention that these 2 pins are not pulled to any voltage internally, so we should not leave them floating in our program. So that means that we don’t need any complex programming, phase sequence tables, frequency control lines and so on because the built-in translator of the A4988 Driver takes care of everything. With the Step pin, we control the mirosteps of the motor and with each pulse sent to this pin the motor moves one step. The Direction pin controls the rotation direction of the motor and we need to connect it to one of the digital pins on our microcontroller. The next two 2 pins, Step and Direction are the pins that we actually use for controlling the motor movements. This capacitor is used for protecting the A4988 driver from voltage spikes. If you are not using the CNC shield then I highly recommend to use a decoupling capacitor across these two pins, the capacitor value should be at least 47uF.
The next two pins GND and VMOT are used to power the Bipolar Stepper Motor, the GND and VMOT pins are connected to a power supply from 8 to 35 Volts. So the pins 1A and 1B will be connected to one coil of the stepper motor and the pins 2A and 2B will be connected to the other coil of the Bipolar Stepper Motor. As you know a Bipolar stepper motor has 4 wires which are internally connected with the two coils. The next 4 pins 1A, 1B, 2A, and 2B are connected with the Bipolar stepper motor. You can connect these two pins with the Arduino’s GND and 5V pins. Let’s start with the GND and VDD pins, these two pins are connected with a power supply of 3 to 5.5V to power up the driver. The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.Īs you can the A4988 stepper motor driver has a total of 16 male headers which are clearly labeled as GND, VDD, 1B, 1A, 2B, 2A, GND, VMOT, DIR, STEP, SLP, RST, MS3, MS2, MS1, and EN. There are no phase sequence tables, high-frequency control lines, or complex interfaces to program. Simply inputting one pulse on the STEP input drives the motor one microstep. The translator is the key to the easy implementation of the A4988. The A4988 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35V and ☒A as per the datasheet. The A4988 is a complete microstepping motor driver with built-in translator for easy operation.

I will also explain how to use the CNC Shield male headers in custom made projects. I will start with the very basics explaining how to control the direction of the Stepper Motor using a very simple Arduino program, and then I will make it a little bit complex by adding a Joystick which can be used to control the stepper Motor.
