Stepper Motor Driver

Jun 18, 2014 1 min read

I was starting to study and use my stepper motor and I needed a control logic board for simplifying the breadboard connections. The aim is to restore the values of the input and then control properly the stepper motor. Directly to the input are connected LEDs in order to see easily see the input signal.

The report related to the project is downloadable here.

Figure 1) Schematic of the driver.

And the physical circuit is presented here below:

Figure 2) Photo of the circuit after soldering.

Figure 3) Photo of the circuit from top.

Finally, I put below the system composed by a STM32F407 Discovery board, the stepper motor driver, the stepper motor and the alimentation device. In the video it’s easy to see every component of the small system implemented.
