How do I wire my A4988?
Wiring A4988 stepper motor driver with Arduino UNO Connections are fairly simple. Start by connecting VDD and GND(next to VDD) to the 5V and ground pins on the Arduino. DIR and STEP input pins are connected to #2 & #3 digital output pins on Arduino respectively. connect the stepper motor to the 2B, 2A, 1A & 1B pins.
What is A4988 stepper motor driver?
The A4988 is a complete microstepping motor driver with built-in translator for easy operation. 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 35 V and ±2 A.
What kind of voltage does a a4988 motor have?
The A4988 motor driver’s output channels are broken out to the edge of the module with 1B, 1A, 2A & 2B pins. You can connect any bipolar stepper motor having voltages between 8V to 35 V to these pins. Each output pin on the module can deliver up to 2A to the motor.
What are the pins on the a4988 driver?
The A4988 driver has total of 16 pins which are as follows: 1. Power Supply Pins: The pin include VDD & VMOT & Pair of GND pins. VDD is employed for driving the interior logic circuitry which may be 3V to 5V whereas VMOT supplies power for the motor which may be 8V to 35 V.
Is the a4988 a microstepping motor driver?
The A4988 is a complete Microstepping Motor Driver with built-in translator for easy operation. The driver has a maximum output capacity of 35 V and ± 2 A. It can operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes. Max. Operating Voltage: 35V Max. Current Per Phase: 2A
How does an Arduino work with an a4988 chip?
Open the Arduino Serial Window at 57600 baud to see messages from your Arduino, then follow along in the code to understand how it works. The A4988 chip supports microstepping – splitting each step into fractions of steps.
