  4. Capacitors
  5. LEDs

Description

This is one circuit schematic of 3.5A Unipolar Stepper Motor Driver using STK672-440BN. According Electronics-lab site describe that compact Unipolar stepper motor driver can drive unipolar motor up to 3.5A and supply range 10 To 50V DC. This compact board is based on STK672-440BN IC from ON semiconductor. The STK672-440BN is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control with Micro-stepping.

Note: This Board can work with motor supply up to 36V DC, for 50V DC Supply Remove IC U2 LM317, and provide 5V Logic supply from external source. Default Enable pin is High for normal operations, pull down 0 to disable the operations, for internal Power on Reset R7 is 0E , C4 can be omit or its fine as it is.
