ماژول درایور L298N چهار کاناله

The drive module has the following characteristics:
1. Integrated two L298N chip can drive four DC motors (reversible, you can use PWM speed control) or two stepper motors
2. Integrated LM2596 DC-DC voltage regulator chip (can output 5V, can give the microcontroller, servos, sensors, routers powered, battery up to 2A)
3. In addition to the board two L298N chip, and then re-integrate a ULN2003 can drive a stepper motor, or four DC motor (start and stop, not reversing), for example when the robot can be controlled as the extinguishing fire fan , no longer need external circuitry.
4. The integrated servo interface leads to signal the end, it is convenient and SCM docking
5. The integrated USB connector can be plugged directly into the router power supply.
6. Support W703N, WIFI router no damage to the car modification, insert the USB, you can use the RXD TXD pin lead, it is convenient to communicate with its own microcontroller
7.5V DC output lead (terminal, pin lead), convenient to the external device needs 5V power supply
Some people can not imagine why you want to integrate, DC-DC voltage regulator?
 
   We all know now as the Smart car, not only to drive the motor, but also supply a range of power microcontrollers, servos, sensors. These peripherals current is also very large. Power has become a big problem! This module is
In order to solve this problem and developed
   for example. Workbench WIFI car, not only to drive two or four DC motors, but have to give MCU control panel, steering gear, routers, and other devices powered. It is generally used in lithium battery 7.4V-12V lithium battery, and these microcontrollers, servos, sensors, routers need 5V, which requires buck regulator. Count, with ordinary 7805, 12V down, 5V, 7805 ate about 7V these devices microcontrollers, servos, sensors, routers, add up to a minimum operating current, 600MA-1A, count the next power 7V * 600MA = 4.2W 7V * 1A = 7W regarded these heat power. Imagine a small, 7805 is to bear so much power, so that heat is very serious (a little exaggeration can be attached to the egg in the pan), the regulator efficiency is only about 40%. Battery energy into heat is lost, and seriously affect battery life. With LM2596 DC TO DC regulator efficiency of about 92%, a good solution to this problem!

DC motors, stepper motor drive module.
Supports 2-way DC motor drive control, 4-phase stepper motor control.
  L298N is a dedicated driver ICs belonging to the H-bridge IC L293D difference is that the output current increases, the power boost. The output current of 2A, the maximum current is 4A, the maximum operating voltage of 50V, can drive inductive loads, such as high-power DC motors, stepper motors, geared motors, servo motors, solenoid valves, etc., in particular its inputs can be directly with the microcontroller Union, which is easily controlled by the microcontroller. When the drive motor, can directly control the stepper motor, and the motor can achieve forward and reverse, to achieve this function simply by changing the input logic levels.
  This module has a small, easy to control features. With this module will give your comfortable motor control, you can respond to the needs of high-power stepper motor problem.
This module can control two-phase, three-phase motors, four phases.
