Features:

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

★ This module can use the built -in 78M05 to take power by the driving power supply part, but in order to avoid damage to the voltage chip, when using the 12V driver voltage, please use external 5V logic power supply.

★ This module uses a large -capacity filter capacitor to protect the diode, which can improve reliability.

★ This module is available in the audience, please take it directly, thank you.

Schematic diagram

Note:

1. When your driver voltage (the identifier in the figure above is 12V input, the actual acceptable input range is 7-12V)
-12V, you can enable the 5V logic power supply that can be carried. When the 5V power supply is used, the+5V in the interface
Do not enter the voltage, but it can lead to 5V voltage for external use.(This is a conventional application!)

2. When the driver voltage is higher than 12V, less than equal to 24V (the chip manual can support 35V, but according to the scriptures
Examination generally 298 conservative application maximum voltage support to 24V is amazing!) At the time, for example, you need to drive the rated voltage to
18V motor.First, you must remove the jumper cap of the 5V output.Then access 5V outside the 5V output port

5V enables a control signal with a level of 5V. When this signal input is valid and the power supply module in the motor drive module is normal, the motor drive module output current.Otherwise, even if the power supply is normal, there is no current on the motor.
Voltage supply to the internal logic circuit of L298N.(This is an unconventional application of high -pressure drivers!)
