ULN2003 Stepper Motor Driver Features
We usually use stepper motors when we need precise control of the motor shaft. These motors can be used in robot arm, 3D printers, CNC machines, etc. 28BJY-48 is a kind of stepper motor. In full step mode, these motors have a 1 to 64 speed reduction gearbox and eachfull 360 degree rotation consists of 32 steps. The ULN2003 driver is commonly used to control these motors.
ULN2003 IC consists of 7 pairs of Darlington transistors, each pair can withstand 500mA and 50V. Th...
A4988 Stepper Motor Driver Features
The A4988 stepper motor driver is intended to drive a bipolar stepper motor. Only by two pins, you can control the rotation direction and rotation steps. Each signal sent by the spin step pin, the motor rotates one step. The key features are:This driver has 200 steps per revolution in full step (1.8 degrees per step).Allowable continuous current per phase without cooling: 1AMaximum current per phase with cooling: 2AMotor voltage: 8 to 35 VThe minimum allowed pulse�...
