L298 Dual H-Bridge Motor Drive

L298 Dual H-Bridge Motor Drive, can one of these be wire so you only use two wires to run a stepper motor.

Stepper motors have 4 wires minimum.

so its connected to an arduino and use two wires to control it instead of 4 wires

The …298 can control a stepper, but its not a good soulution, as you cannot control current very well.
Better is to use a a stepper motor controller.
