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.

Note that the motor’s speed and direction interfaces have been connected. D3 is for controlling the speed of motor A, and D12 is for controlling the direction of motor A. D11 is for controlling the speed of motor B, and D13 is for controlling the direction.

Just simply stack the shield onto UNO board to power the shield and UNO board. The 3 kinds of power supply are as follows:

• You can power the board via the black DC jack on the UNO R3 board.

• Or power the board through the VIN GND female header of 2.54mm pitch on the shield.

• Supply the power through the green terminal blocks on the shield.

The L298P shield also comes with through-hole welding space, so you are able to weld the electronic elements to design a variety of prototyping circuits.

Pay close attention to:

The shield comes with a slide switch. When power via the DC jack on the UNO R3 and female headers on the L298P shield, the slide switch is not available.

But when power via the green terminal blocks on the L298P shield, the slide switch can be used as power control switch.
