Almost the same as the previous link for the L6208:

About the L6208:

The L6208 has indipendent Signal and Power Ground.

Beware to never shutdown the signal power supply (+ 5V) before
the stepper power supply, that will destroy power circuits.

Cooling fan mandatory if current > 1A.

Best regards,

Luciano
