Voltage to L298N internal logic circuit power supply. Otherwise, even if the power supply is normal, there is no current on the motor. When the signal input is valid, and when the power supply is normal in the motor drive module, the motor drive module outputs the current.
The 5V enables the power to be a control signal with a level of 5V. Then 5V is accessed outside the 5V output port You must first remove the board 5V output to enable the jumper cap. When the maximum voltage is applied to the maximum voltage of 298 conservative applications to 24V, for example, the motor with a rated voltage of 18V shall be driven. (the chip manual proposes to support 35V, but according to the book When the driving voltage is higher than 12V, it is less than or equal to 24V The power supply does not input voltage, but can yield 5V voltage for external use.Ģ. When you are driving voltage (above logo for the 12 v input, can actually accept input range is 7 to 12 v) for 7 v to 12 v, can make to onboard power supply 5 v logic, when using the onboard after 5 v power supply, interface of + 5 v This module USES a large capacity filter capacitance, a continuation protection diode, can improve reliability.ġ. 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 L298N as the main drive chip, with strong driving ability, low heat and strong anti-interference ability.
