3 stepper motors from 1 board
i'm akshay , i'm working on project on controlling 3 stepper motors. i have ordered an arduino mega 2560 board, along 3 easy drivers (sparkfun) , 3 5v stepper motors. can run 3 motors no external supply (i.e on supply provided board) results? board overloaded? that depends on how current stepper motors require. if run arduino usb power have 400 ma left on other devices. if run arduino off external power can draw 900 ma before regulator overheats. i'm guessing need external power. what exact steppers using?
