3.5A Unipolar Stepper Motor Driver

3.5A Unipolar Stepper Motor Driver

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

How to use soft PWM in RPi.GPIO 0.5.2a pt 2 – led dimming and motor speed control

In part 1 of this series, we looked at the basic commands for using software pulse-width modulation (PWM) in RPi.GPIO 0.5.2a and higher. In this article we’ll get a bit more hands-on and into some practical applications for it. It’s all very well being able to make nice square-wave pulses on an oscilloscope, but what’s
