L298 MOTOR DRIVER BOARD

L298 Motor Driver Module is a high-power motor driver perfect for driving DC Motors and Stepper Motors. It uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. It can control up to 4 DC motors, or 2 DC motors with directional and speed control

This motor driver is perfect for robotics and mechatronics projects and perfect for controlling motors from microcontrollers like Arduino, switches, relays, etc. Perfect for driving DC and Slepper motors for micro mouse, line-following robots, robot arms, etc.

An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM),

Working:

Pulse Width Modulation is controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied too heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM.

FEATURES:

• Maximum motor supply current: 2A per motor.
• Current Sense for each motor.
• Heatsink for better performance.
• Power-On LED indicator.
• Double H bridge Drive Chip: L298N.

APPLICATIONS:

• Robotic Cars
• Robotic Arms
• Controlling the motor’s speed and direction
