About this item

The OSOYOO Motor Shield is based on the L293DD (datasheet), which is a monolithic integrated high voltage,high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.To prevent board damages, all driver lines are diode protected from back EMF. The maximum supply voltage supported by this board is 20V

It uses a L293DD chip which deliveries output current up to 1.2A each channel. it requires a 6V to 15V power supply to power the motor and also includes an on-board 5V voltage regulator for powering the driver chip. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently.

You can use UNO R3 microcontroller and add external components to complete a variety of amazing experiments, such as smart robot DIY. When DIY your robot, it is necessary to use the motor driver board to drive the DC motors, however, sometimes need to connect the motor drive board to UNO using lots of jumper wires, pretty inconvenient.

The Motor shield can be powered directly from Arduino or from external power source. It is strongly encouraged to use external power supply to power the motor shield.

This board also provides direction LED indicators for both channels and this is very usefull during setup stage to verify the firmware behaviour; the led indicators work also without appling a real motor to the output.
