直流电机驱动芯片采用Ｌ２９８．支流电机驱动就是利用ＰＷＭ脉宽控制Ｌ２９８电流输出大小，从而达到控制电机的目的-Motor Driver IC using L298. Tributaries is the use of motor-driven PWM pulse width control L298 current output size, so as to achieve the purpose of the electrical control-DC motor driver chip L298. Tributary of the motor drive is using the PWM pulse width control L298 current output size, so as to achieve the purpose of controlling motor-Motor Driver IC using L298. Tributaries is the use of motor-driven PWM pulse width control L298 current output size, so as to achieve the purpose of the electrical control
