This module can use the built-in 78M05 to take power through the drive power supply part, but in order to avoid the damage of the voltage regulator chip, when using the drive voltage greater than 12V, please use the external 5V logic power supply. This module uses a large-capacity filter capacitor and a freewheeling protection diode to improve reliability. This module is available in the whole game, please take a photo directly, thank you. Precautions: 1. When your driving voltage (the above picture is 12V input, 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 , +5V in the interface Do not input voltage to the power supply, but can draw 5V for external use. (This is a regular application!) 2. When the driving voltage is higher than 12V, less than or equal to 24V (the chip manual can support up to 35V, but according to experience, 298 conservative application of maximum voltage support to 24V is very great!), for example, to drive a motor with a rated voltage of 18V . First, the jumper cap with the onboard 5V output enable must be removed. Then, 5V5V is enabled outside the 5V output port to enable a control signal with a level of 5V. When this signal input is valid and the power supply in the motor drive module is normal, the motor drive module outputs current. Otherwise, there is no current on the motor even if the power supply is normal. The voltage supplies power to the L298N internal logic circuit. (This is a non-conventional application of high voltage drive!)
