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...

74HC4051 8-Channel Analog Multiplexer Features The 74HC4051 8-Channel analog multiplexer module can be used when there are many analog inputs in a circuit. In this case, one of these inputs needs to be selected and processed each time. This multiplexer can be used to select from 8 analog inputs. There are three S0-2 pins, which by giving appropriate values, one of the analog inputs is set as the output on the Z pin. 74HC4051 8-Channel Multiplexer Pinout This module ...

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�...

TMC2100 Stepper Motor Driver Features The TMC2100 driver is one of the most popular stepper motor drivers available on the market. It works similar to the DRV8825 and A4988 drivers.This module is intended to drive a bipolar stepper motor. Only by using two pins, the rotation direction and rotation steps can be controlled. Each signal sent by the spin step pin, the motor shifts one step. The key features are:This driver has 200 steps per revolution in full step (1.8 degrees per step).Allowable continuou...
