Tips:Now the market appears imitation of the company's modular products, the company's production of L298 chip is a new authentic chip, aluminum foil is used in two 35V 220UF high-voltage high-capacity capacitors, and imitation of the module is used to renovate the 2-chip, 35V 100UF and 10V 100UF low-voltage low-capacity capacitor. Please understand when buying. In order to avoid being deceived, the board burned all.

Features:

The module uses ST's L298N as the main driver chip, with a strong driving ability, low heat, anti-interference ability.

This module can use the built-in 78M05 to drive power through the drive part of the power supply, but in order to avoid damage to the chip damage, when using more than 12V drive voltage, please use an external 5V logic power supply.

This module uses large capacity filter capacitor, freewheeling protection diode, can improve the reliability.

This module has the goods in the audience, please directly photographed, thank you.

Precautions:

1. When your drive voltage (The above figure is marked as 12V input, the actual acceptable input range is 7-12V) For 7V-12V, you can enable onboard 5V logic power supply, when using the onboard 5V power supply, the interface of the +5 V
Power supply does not input voltage, but can lead to 5V voltage for external use. (This is the regular application!)

2. When the drive voltage is higher than 12V, less than or equal to 24V (chip manual can be supported to 35V, but according to the

Test general 298 conservative application of the maximum voltage support to 24V has been very great! ), Such as to drive the rated voltage

18V motor.First, you must remove the on-board 5V output enable jumper cap. And then 5V in the 5V output port access 5V

5V enable that isOne level is 5Vcontrol signal, When this signal input is valid, andmotor drivenWhen the power supply in the module is normal,motor drivenModule output current. Otherwise even if the power supply is normal, there is no current on the motor.
Voltage to the L298N internal logic circuit power supply. (This is the unconventional application of high voltage drive!)
