L298N MOTOR DRIVER ARDUINO SERVO FULL
The L298P contains two full H-Bridge drive channels that provide full speed and direction control. In general, if you are using the motors, you should plan to bring the motor power in on the VMS power connector for the most stable operation. If you have the OPT jumper in place and power coming on the DC Jack on the Arduino, it will work but the DC motor noise will be coupled into the 5V logic power supply and may cause eradicate behavior and so it is not really recommended. Note that if you have the OPT jumper in place and USB connected, but there is no power on the VMS motor connector, it will try to use the USB power to power the DC motors. For this 5V regulator to function, the VMS voltage must be at least 6.3V. This isolates any servo electrical noise from getting back into the main 5V that powers the logic. This motor power is fed to a 5V regulator that is mounted to the bottom of the shield. VMS = Motor Vcc which must be between 4.8 and 24V.If you are using this input to power the Arduino by installing the ‘OPT’ jumper, the maximum input voltage on this terminal should be limited to 12V to avoid overheating the Arduino regulator. The VMS is the positive motor voltage which can range from 4.8 to 24V. The motor power comes in on the 2-pos screw terminal. If powering the Arduino off the shield, the DC power jack on the Arduino should not be used to avoid a power conflict, but the USB can be used. To use this option, the motor power input must be at least 6.5V to feed the regulator. When the jumper is installed, the power from the motor VMS power connector is connected to the Vin pin on the Arduino which feeds the Arduino on-board 5V regulator. When this jumper is removed, the Arduino must be powered separately. 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.
L298N MOTOR DRIVER ARDUINO SERVO BLUETOOTH
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.
