stepper motor interfacing with spartan 3an fpga


Posted on Feb 6, 2014

The Spartan-3an board has external stepper motor interfacing, indicated as in Figure. Stepper Motor is driven by ULN2803A. It is a high-voltage, high-current Darlington transistor array. ULN2803 is used as a driver for port I/O lines, drivers output connected to stepper motor, PTB connector provided for external power supply if needed.
