Dual H-Bridge Motor Driver Shield, based on H-bridge driver Chip L298N Motor Driver Integrated Circuit, is a usefull module for controlling of robotics and mechanics. It can drive two brushed DC motors or one 4-wire two-phase stepper motor. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads 
such as relays, solenoids, DC and stepping motors. Both motors can be driven simultaneously while set to a different speed and direction.
