Features:

ST's L298N as the main driver chip has the characteristics of strong driving ability, low calorific value and strong anti-interference ability.:

You can use the built-in 78M05 to get power through the driving power supply part, but in order to avoid damage to the voltage regulator chip, when using a driving voltage greater than 12V, please use an external 5V logic power supply.:

Use large-capacity filter capacitors and freewheeling protection diodes to improve reliability.:

Precautions:

1. When your driving voltage (the above picture is marked as 12V input, the actual acceptable input range is 7-12V) is 7V:

When -12V, the onboard 5V logic power supply can be enabled. When the onboard 5V power supply is used, the +5V in the interface:

The power supply does not need to 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, less than or equal to 24V (it is suggested in the chip manual that it can support up to 35V, but according to the:

In general, 298 conservative application maximum voltage support to 24V is already great! ), for example to drive a rated voltage of:

18V motor. First, the jumper cap that enables the onboard 5V output must be removed. Then connect 5V externally to the 5V output port:

The voltage supplies power to the internal logic circuits of the L298N. (This is an unconventional application of high voltage drive!) :
