Stepper Motor Driver Board ULN2003 for Arduino 5V 4 Phase 5 Line

 

Introduction

• Standard double panel design,fine workmanship, board size:38mm X 30mm
• Use ULN2003 drive chip,500mA
• In stepping motor port,four channels highlight SMD green LED diode indicates working status
• In DC motor port,one channel highlight SMD green LED diode indicates working status
• Power light:highlight red SMD LED diode
• Equipped with stepping motor standard interface and DC motor standard interface,can directly call waiting when using
• Choose through red short circuit hat,support different working voltage motors
• Connect short circuit hat,choose 5V as the working voltage for steeping motor/DC motor
• Take off short circuit hat,steeping motor/DC motor can choose external voltage for power supply through pins 

Wiring method

1. Wiring method for stepping motor

Left 1 N 1 and 1 N 4 connect to the four corresponding IO wires of MCU
The right black pins are defined from top to VCC,A,B,C,D connect to the concentric line, phase A,B,C,D of stepping motors
 
2.Wiring method for DC motor

Left 1 N1 and 1 N 4 connect correspondingly to the four IO wires of MCU
The right black pins are defined as:below is VCC
 
Power supply method

• Connect short circuit hat, choose 5V as the working voltage for stepping motor/DC motor
• Take off short circuit hat, stepping motor/DC motor can choose external voltage for power supply via pins
• Speed down stepping motor
• Diameter:28mm
• Voltage:5V
• Stepping angle:5.625 X 1/64
• Speed reduction ratio:1/64
• Five lines four phases,can be driven by common uln2003, and can be used as connecting two phase;can be used with PCB board,direct plug and socket,easy to use on PCB board
