Using L298N as the control chip, the module has such characteristics as strong driving
ability, low calorific value and strong anti-interference ability.
This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage
of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage.
Using large capacity filter capacitor, this module can follow current to protect diodes, and improve the reliability
