L298N Motor Drive Board Module DC Stepper Motor Motor Smart Car Robot Accessories
Features:
★ This module uses ST's L298N as the main drive chip, which has the characteristics of strong drive capability, low heat generation and strong anti-interference ability.
★ This module can use the built-in 78M05 to work through the drive power supply, but in order to avoid damage to the voltage regulator chip, when using a drive voltage greater than 12V, please use an external 5V logic power supply.
★ This module uses large-capacity filter capacitors and freewheeling protection diodes to improve reliability.

Precautions:
1. When your drive voltage (marked as 12V input in the above figure, the actual acceptable input range is 7-12V) is 7V-12V, you can enable the onboard 5V logic power supply. After using the onboard 5V power supply , The 5V power supply in the interface does not require input voltage, but it can lead to 5V voltage 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 suggests that it can support 35V, but according to experience, it is great to support 24V with conservative application voltage!), for example, to drive a motor with a rated voltage of 18V. First, the jumper cap of the onboard 5V output enable must be removed. Then connect the 5V enable, that is, a control signal with a level of 5V, to the 5V output port. When this signal input is valid and the 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 power to the internal logic circuit of the L298N. (This is an unconventional application of high voltage drive!)
