2 DC motor driving module positive and reverse PWM speed adjustment dual H bridge step motor mini is better than L298N

2 DC motor driving module positive and reverse PWM speed adjustment dual H bridge

Step motor mini L298N

Product introduction: The motor driver module is very suitable for smart cars, toy cars, robots, etc. with battery power supply. The power supply voltage is 2V ~ 10V, which can drive two DC motors or 1 4 -line and 2 -to -step motor at the same time, which can be realized to achieve realization.The function of forward and reverse and speed regulation can continue to currently reach 1.5A per number of currents, and the peak current can reach 2.5A. It has heat protection and can automatically recover.

L298N, perfect replacement.This product is sold for sale, each blockbuster = 5*8 = 40 small film

Product highlights:

1. Adopt imported original professional motor driving chips. The built -in low -conducting internal resistance MOS switch tube is extremely small, no heat sink, small volume, power saving, is an ideal choice for your battery power supply.

(L298N is the crystal pipe switch inside, with low efficiency, high heating, heat dissipation, and bulky volume. The L298N on the market is very easy to burn and bad, and no original chip is used. This product can be perfectly replaced.

2. Double road 1.5A*2, the peak current can reach 2.5A, and the built -in overheating protection circuit. Do not be afraid that the motor is blocked and burn out. The temperature will automatically recover after the temperature drops.(At present, the voltage and current on the market on the market are within this range)

3. Small volume, light quality, 0 standby current, is the ideal choice for your model car

Product parameters:

Driven by the double -road H bridge motor, you can drive two DC motors at the same time or one 4 -line two -sided step -by -step motor;
Module power supply voltage 2V-10V;

material:

Inx connection machine IO or other signal sources, Motor-A and Motor-B connect to motor.

DC motor drive logic true value table:

Note:

1. Power positive and negative electrodes will definitely cause circuit damage.

2. The short -circuit or output end of the output is out of the ground, and the chip will be kept hot when the motor is blocked. However, the chip will be destroyed when it is close to or exceeded 10V voltage and the peak current exceeds 2.5A.
