This stepper motor control application is based on L298 power stage IC. Double sided factory made PCB's will be shown latter. Clock, and direction signals are generated by ARM7 LPC2131 board from previous project. L297 IC is responsible for generating stepper motor phases sequence, timings. L298 is a power stage, which basicaly is two H bridges, enabling to drive DC or stepper motor. My new PCB has two L298, L297 is replaced by atmega64 AVR microcontroller. I hope I'll find time to document and publish this project. Right now this is what I have:
