Zhiyitech L298n Stepper Motor Drive Module For Arduino Smart Robot Car Part Diy Electronic Kit Project
1. 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 the onboard power supply 5 v logic, when using the onboard after 5 v power supply, the interface of + 5 v
The power supply does not input voltage but can yield 5V voltage for external use.
2. When the driving voltage is higher than 12V, it is less than or equal to 24V
(the chip manual proposes to support 35V, but according to the book
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.
You must first remove the board 5V output to enable the jumper cap. Then 5V is accessed outside the 5V output port
The 5V enables the power to be a control signal with a level of 5V. 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. Otherwise, even if the power supply is normal, there is no current on the motor.
