This is a 4x22W amplifier 4Ohm which is young for a PCI Desktop slot and can be diagnosed and controlled by an internal USB connector. This project is still in development stage This card is made with a specialized circuit in Class D with I2C control interface produced by TexasInstruments TAS5414 QFP64 and a ATmega8 controller

This is a usb controller for 3 engines unipolar step by step, you can move completely independent, and in terms of speed of rotation sense and the coordinated which should be. The position an engine can take value between -2147483648 and 2147483647 Minim velocity = 0.015 steps/second Maximum velocity = 1000 steps/second Here i posted a brief presentation of the controller in the prototype phase, it will arrive in stores in a short period. It is designed around an ATmega8 microcontroller with USB1.1 software interface and drivers that are used is ULN2003 This is the interface for the PC, to control in real-time the controller: And this is the prototype controller board: In the next image is described command method : From Digital electronics and programing Update for PC program, add new function: Soon available for buy.

This project is designed for control 3 motors stepper independently with only one ATmega8 mocrocontroller This project has been designed for unipolar engines The interface is Serial 19200b/s For Bipolar engines Download entire project
