AVT2745 A +

A simple and inexpensive driver for the stepper motor. The layout was designed to control the stepper motor removed from the old printer. The operation of the device was checked practically by coupling it with a microphone stand. The kit is responsible for ejecting and inserting the tube into which the microphone is mounted.
The controller uses a 90S2313 microprocessor. The field effect transistors are used as actuators for direct control of the motor. The system is operated by two buttons, two others are fully function of the final button. The operating mode is selected by DIP-SWITCHES

The device is highly recommended to designers using stepper motors and stage and stage staff

Selected parameters of the controller:

• cooperation with a stepper motor powered by 4 + 1
• G? RA / D?
• final buttons
• opportunities ?? to connect an acoustic signal
• programming of the work mode
• power supply - 7-25 V
• in the set a printed circuit board, programmed layout and documentation
  A version with a set of elements is available for self-assembly
