产品特点:
★ 本模块使用ST公司的L298N作为主驱动芯片,具有驱动能力强,发热量低,抗干扰能力强的特点。
★ 本模块可以使用内置的78M05通过驱动电源部分取电工作,但是为了避免稳压芯片损坏,当使用大于12V驱动电压的时候,请使用外置的5V逻辑供电。
★ 本模块使用大容量滤波电容,续流保护二极管,可以提高可靠性。
★ 本模块全场有货,请直接拍下即可,谢谢。

注意事项:
1.当你的驱动电压(上图标识为12V输入,实际可以接受的输入范围是7-12V)为7V
-12V的时候,可以使能板载的5V逻辑供电,当使用板载5V供电之后,接口中的+5V
供电不要输入电压,但是可以引出5V电压供外部使用。(这种即为常规应用!)
2.当驱动电压高于12V,小于等于24V(芯片手册中提出可以支持到35V,但是按照经
验一般298保守应用最大电压支持到24V已经很了不起!)时,比如要驱动额定电压为
18V的电机。首先必须拔除板载5V输出使能的跳线帽。然后在5V输出端口外部接入5V
5V使能即 一个电平为5V的控制信号,当此信号输入有效时,且电机驱动模块中电源供电正常时,电机驱动模块输出电流。否则即使电源供电正常,电机上也无电流。
电压对L298N内部逻辑电路供电。(这种是高压驱动的非常规应用)
英文描述:
Module name : dual H bridge motor drive module
Work mode : H bridge drive (double road)
Main control chip : L298N
Packaging : electrostatic bag
Logical voltage : 5V
Drive voltage : 5v-35v
Logical current : 0mA-36mA
Driving current : 2A(MAX single bridge)
Storage temperature : - 20 ℃ to + 135 ℃
Maximum power : 25W
Weight : 30 g
Peripheral dimensions : 43*43*27mm
Product features:
This module USES L298N as the main drive chip, with strong driving ability, low heat and strong anti-interference ability.
Through this module can use the built-in 78 m05 drive power supply parts of their work, but in order to avoid the voltage regulator chip damage, when using the driving voltage is greater than 12 v, please use the external power supply 5 v logic.
This module USES a large capacity filter capacitance, a continuation protection diode, can improve reliability.
Notes:
1. When you are driving voltage (above logo for the 12 v input, can actually accept input range is 7 to 12 v) for 7 v to 12 v, can make to onboard power supply 5 v logic, when using the onboard after 5 v power supply, interface of + 5 v
The power supply does not input voltage, but can yield 5V voltage for external use.
?6?7
2. When the driving voltage is higher than 12V, it is less than or equal to 24V
(the chip manual proposes to support 35V, but according to the book
When the maximum voltage is applied to the maximum voltage of 298 conservative applications to 24V, for example, the motor with a rated voltage of 18V shall be driven.
You must first remove the board 5V output to enable the jumper cap. Then 5V is accessed outside the 5V output port
The 5V enables the power to be a control signal with a level of 5V. When the signal input is valid, and when the power supply is normal in the motor drive module, the motor drive module outputs the current. Otherwise, even if the power supply is normal, there is no current on the motor.
