Stepper Motor Driver with L6474 and Rotary Encoder

Project Description: This board implements a stepper motor driver and controller together using L6474 stepper driver chip. Board also has quadrature encoder input to make closed loop control possible. Additionally, it continuously read 5 NPN sensors while connecting to a host via RS232 port allowing all the control and configuration be made.

Key Components:

  • L6474
  • PIC18F4431
  • MAX232
  • LM2594
  • SFH6186-5


  • Bipolar Stepper Driver
  • Quadrature Encoder Interface
  • 5 NPN Sensor Input
  • RS232 Port
  • 9V … 24V Power Input
