How do I connect my A4988 to my Arduino?
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.
What is A4988 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 is the meaning of Arduino?
What Does Arduino Mean? Arduino refers to an open-source electronics platform or board and the software used to program it. Arduino is designed to make electronics more accessible to artists, designers, hobbyists and ayone interested in creating interactive objects or environments.
What kind of motor does an Arduino a4988 use?
An A4988 can control a single motor and supply up to 35V at 1.5A. An Arduino motor shield can drive 2 DC Motors or 1 stepper motor at up to 12V and 4A/2A. An A4988 needs mounting. A motor shield drops straight in. There are other options, including getting the ICs and doing it your self.
What are the safety features of the a4988 driver chip?
The A4988 driver chip has several safety functions built-in like overcurrent, short circuit, under-voltage lockout, and over-temperature protection. You can find more specifications in the table below.
Which is microstepping driver for Arduino stepper motor?
At the heart of the A4988 driver you will find a chip made by Allegro MicroSystems: the A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection. This integrated motor driver makes interfacing with a microcontroller super easy as you only need two pins to control both the speed and the direction of the stepper motor.
Is the a4988 a dual stepper motor?
The A4988 is dual because it has two H bridges, one for each pair of wires attached to the stepper motor. The A4988 specifically can drive up to 1 amp continuous, and up to 2 with extra cooling. The chip also handles the chore of remembering the correct sequence of H bridge changes to make your stepper motor move.
