L298N Motor Driver Module

• This L298N Motor Driver Module is a high power motor driver module for driving DC and Stepper Motors.
• It can control up to 4 DC motors, or 2 DC motors with directional and speed control.
• The L298N Motor Driver module consists of an L298 Motor Driver IC, 78M05 Voltage Regulator, resistors, capacitor, Power LED, 5V jumper in an integrated circuit.
• 78M05 Voltage regulator will be enabled only when the jumper is placed. When the power supply is less than or equal to 12V, then the internal circuitry will be powered by the voltage regulator and the 5V pin can be used as an output pin to power the microcontroller. The jumper should not be placed when the power supply is greater than 12V and separate 5V should be given through 5V terminal to power the internal circuitry.
• ENA & ENB pins are speed control pins for Motor A and Motor B while IN1& IN2 and IN3 & IN4 are direction control pins for Motor A and Motor B.
• Alternate Driver Modules:�TMC2130, DRV8825, A4988, L9110S, DRV8711

L298N Module Pinout Configuration

• IN1 & IN2Motor A input pins. Used to control the spinning direction of Motor A.
• IN3 & IN4 Motor B input pins. Used to control the spinning direction of Motor B.

Input1	Input2	Spinning Direction
Low(0)	Low(0)	Motor OFF
High(1)	Low(0)	Forward
Low(0)	High(1)	Backward
High(1)	High(1)	Motor OFF

• ENA Enables PWM signal for Motor A
• ENB Enables PWM signal for Motor B
• OUT1 & OUT2 Output pins of Motor A. You can connect any DC motor that runs on 5 to 46 volts to these pins.
• OUT3 & OUT4 Output pins of Motor B. You can connect any DC motor that runs on 5 to 46 volts to these pins.
• VS is the main power input for the motors. On many modules, this pin is labeled as +12V, but it can actually handle a wide range of DC voltages, from 5V up to 46V. However, it’s important to understand that the voltage your motors actually receive will be a bit lower than what you supply to the VS pin. This is because the internal H-Bridge transistors inside the L298N cause a voltage drop of about 2V.
• VSS  is the power input for the internal logic circuitry of the chip. This logic circuitry needs a steady 5V to operate. You can supply this 5V in one of two ways. One option is to connect an external 5V power supply directly to the VSS pin. The other option is to use the onboard 5V voltage regulator, which takes power from the motor supply (VS) and automatically provides 5V to the logic circuits. When you use the onboard regulator, you don’t need to connect anything to the VSS pin yourself.
• GND pin is the common ground connection for the module. Both the motor power supply and your Arduino must share a common ground through this pin.
