ขับมอเตอร์ได้ 2 ตัวแบบแยกอิสระ สามารถควบคุมความเร็วมอเตอร์ได้ ใช้ไฟ 5 โวลต์ สามารถรับไฟเข้า 7-35 โวลต์ได้ มีวงจรเรกูเลตในตัว ขับกระแสสูงสุดได้ 2A

Motor Drive Module L298N

This module is integrated with a built-in 5V power.When the drive voltage is 7V-35V, it can enable the onboard 5V logic power supply;afterthe power supply,don't input voltage in the interface+5V power supply,but you can lead the 5V for external use. 
when ENA enable IN1 IN2 control OUT1 OUT2 
when ENB enable IN3 IN4 control OUT3 OUT4

Applied cases: 
1 Driving stepper motor 
The connection of driving a common 4 line 2 phase electric motor is shown in below figure 
after enable ENA ENB 
Input the following driving timing from IN1-IN4，then the speed and direction of the stepper 
motor can be controlled

2 Driving DC motor 
Because the module is drived by double H bridge,it can drive two motors simultaneously. 
The connecting method is shown inbelow figure 
after enable ENA ENB 
You can imput the speed and direction of PWM signal drive motor 1 from IN1 IN2 
You can imput the speed and direction of PWM signal drive motor 2 from IN1 IN2 
The signal is shown in the figure
