SMA7029M appears on a number of salvaged boards from photo copy machines. I am not sure where to start connecting with Arduino and can't find a tutorial. Would you please take a look at the data sheet http://www.allegromicro.com/en/Products/Part_Numbers/97024/97024.pdf Is SMA7029M compatible with Arduino? My motors are high voltage/current.
My motors are high voltage/current.
Can you please be more specific? How many Volts? How many Amps?
The stepper is nominal 24v and the chip, up to 46v. I have ordered L298 as you suggested in a previous post but I happened to run across these while salvaging. The problem has been too much current for the driver chip.
