To select this, there is a jumper near the electrolytic cap labeled ‘OPT’. The Arduino can be powered separately using the normal USB or DC power connector or it can also be powered from the Shield. The Arduino 3.3V is brought up to the shield and is available on the 2 Bluetooth connectors. This ensures that they have good clean 5V power independent of what the motors are doing. It is also used to power the logic portion of the L298P chip. The Arduino 5V is brought up to the shield and is available on the 6 sets of red sensor 5V pins, the yellow Ping connector for Ultrasonic Rangefinders and the 2 blue digital connectors. Can optionally power attached Arduino off the shield.Stacking female connectors for supporting another daughter card.6 Analog/digital pins brought out to 3-pin headers with 5V and Gnd available for each input for easy sensor hookup.Ultrasonic Range Finder Ping connector.Drive 1 servo motor with a dedicated 5V regulated power. Built-in Schottky diodes to protect against motor back EMF.Drive 2 DC motors at 4.8-24V at up to 2A peak (2.5A peak) current.KEY FEATURES OF L298P MOTOR DRIVER SHIELD: The FunduMoto L298P Motor Driver Shield is a multi-featured motor shield based around the L298P driver chip and fits Arduino Uno or other Arduino with compatible I/O pins.
