Scope of application: beginner, experiment equipment platform, interactive electronic, robots, etc.

Characteristics: more functions, convenient operation, powerful drive library support and update.

Weakness: the I/O occupy more at the same time four road motor under the condition of relatively less I/O (version), small power.

To drive dc motor or 2 road 4 step motor at the same time also can drive 2 road steering gear, support for the latest UNO, Mega 2560

You can match like this:
Four dc motor and two road steering gear drive
Driven by two dc motors and stepper motor and two lines of steering gear
Driven by two stepper motors and two road steering gear
