Product features:

★ This module uses L298N as the main driver chip, which has the characteristics of strong driving ability, low heat output and strong anti-interference ability.

★ This module can use the built-in 78MO5 to power through the drive power supply, but in order to avoid damage to the voltage regulator chip, when the drive voltage is greater than 12V, please use the external 5V logic power supply.

★ This module uses large capacity filter capacitor and continuous current protection diode, which can improve reliability.

Notes:

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 onboard power supply 5 v logic, when using the onboard after 5 v power supply, 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.
