L298 L298N L298D Motor Driver Module

 250

This L298N Based 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, switches, relays, etc. Perfect for driving DC and Stepper
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). Pulse Width Modulation
is a means of 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 􀃖owing 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.

Pins:

1. Out 1: Motor A lead out
2. Out 2: Motor A lead out
3. Out 3: Motor B lead out
4. Out 4: Mo (Can actually be from 5v-35v, just marked as 12v)

5. GND: Ground
6. 5v: 5v input (unnecessary if your power source is 7v-35v, if the power source is 7v-35v then it can act
as a 5v out)
7. EnA: Enables PWM signal for Motor A (Please see the “Arduino Sketch Considerations” section)
8. In1: Enable Motor A
9. In2: Enable Motor A
10. In3: Enable Motor B
11. In4: Enable Motor B
12. EnB: Enables PWM signal for Motor B (Please see the “Arduino Sketch Considerations” section)

 

Usage:

H-bridges are typically used in controlling motors speed and direction but can be used for other projects such as
driving the brightness of certain lighting projects such as high powered LED arrays.
