This drive module has the following characteristics:
1 integrated two L298N chip can drive four DC motors (can be a positive inversion, can be used PWM speed) or two stepper motor
2 integrated DC-DC LM2596 regulator chip (you can output 5V, you can give the microcontroller, servo, sensor, router power supply, the maimum battery up to 2A)
. in addition to the board on the second chip L298N chip, and then integrated ULN2003 to drive a stepper motor can be, or four DC motor start and stop, is not reversed) such as in etinguishing fire robot can control fire etinguishing fan, no need to eternal circuit.
4 integrated steering engine interface, leads to the signal terminal, it is convenient to dock with the microcontroller
5 integrated USB power supply socket can be directly inserted router.
6. Support W703N, WiFi router car without damage modification, insert the USB and the RD TD pin lead, very convenient of with its own single chip communication
LeadsSeven5V DC output terminal (terminal pins, power supply device is convenient to elicit) eternal needs 5V power supply
Some people can not figure out why the integration, DC-DC regulators?
We all know that now as a smart car, not only to the motor drive, but also to supply SCM, steering gear, sensors and a series of power supply. And the current is very large. Power supply has become a big problem! This module is
Research and development to solve this problem
For eample. As a WIFI car, not only to drive two or four DC motor, but also to the MCU control board, steering gear, routers, and other devices powered by. General use of lithium is 7.4V-12V lithium battery and the microcontroller, actuators, sensors, routers and other need 5V, which requires step-down regulator. Count, with ordinary 7805, 12V to, 5V, 7805 ate approimately 7V these single chip device, actuators, sensors, router, add up to minimum operating current, 600MA-1A, power 7V*600MA=4.2W 7V*1A=7W these heating power are considered. Imagine small, 7805 is bear so much power and heat is very serious (a little eaggeration can be attached to the pan boiled the), Zener efficiency is only 40%. Battery energy to heat loss, and seriously affect the battery life. With DC TO DC LM2596 regulator efficiency of about 92%, a good solution to this problem!

L298N is a special driver IC, which belongs to the H Bridge integrated circuit. The difference between L293D and is that the output current is increased and the power is enhanced. Its output current is 2A, the maimum current is 4A, the maimum operating voltage is 50V, which can drive inductive load, such as high power DC motor, stepping motor, deceleration motor, servo motor, solenoid valve, etc., especially the input can be directly connected with the microcontroller, which is easily controlled by the microcontroller. When the DC motor is driven, the stepper motor can be directly controlled, and the motor can be turned and inverted, so that the function can only change the logic level of the input terminal.
This module has the characteristics of small size and convenient control. Using this module will enable you to control the motor, you can respond to the need for a large power stepper motor.
This module can control the two phases, three-phase, four phase of the motor.
