Motor Drive Module L298N
ขับมอเตอร์ได้ 2 ตัวแบบแยกอิสระ สามารถควบคุมความเร็วมอเตอร์ได้ ใช้ไฟ 5 โวลต์ สามารถรับไฟเข้า 7-35 โวลต์ได้ มีวงจรเรกูเลตในตัว ขับกระแสสูงสุดได้ไม่เกิน 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 supplydont input voltage in the interface+5V power supplybut 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 bridgeit 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
