Features:
*This module USES L298N as the main drive chip, with strong driving ability, low heat and strong anti-interference ability.
*Through this module can use the built-in 78 m05 drive power supply parts of their work, but in order to avoid the voltage regulator chip damage, when using the driving voltage is greater than 12 v, please use the external power supply 5 v logic.
*This module USES a large capacity filter capacity, a continuation protection diode, can improve reliability.

Precautions:
1. When your driving voltage(marked as 12V input in the above picture, the actual acceptable input range is 7-12V) is 7V
When-12V, the onboard 5V logic power supply can be enabled. After using the onboard 5V power supply, the+5V in the interface
No input voltage is required for power supply, but 5V voltage can be drawn out for external use.(This is a regular application!)
2. When the driving voltage is higher than 12V and less than or equal to 24V(the chip manual states that it can support up to 35V, but according to experience It has been tested that the maximum voltage of 298 conservative applications can support up to 24V), for example, if you want to drive the rated voltage to
18V motor. First, you must remove the onboard 5V output enable for jumper cap. Then connect 5V externally to the 5V output port
5V enable is a control signal with a level of 5V. When this signal input is valid and the for power supply in the motor drive module is normal, the motor drive module outputs current. Otherwise, even if the power supply is normal, there will be no current on the motor.
The voltage supplies the L298N internal logic circuitry.(This is an unconventional application of high voltage drive)
