2DC motor drive module Positive and negativePWMSpeed control doubleHbridge

Stepper motor MiniL298N 

Product Description: Motor drive module is ideal for battery-powered smart car, toy car, robot and other use, power supply voltage2V ~ 10V, Can simultaneously drive two DC motors or1One4line2Phase stepper motor, can achieve positive and negative and speed control function, each current can reach1.5AContinuous current, peak current reachable2.5A, With thermal protection and can be automatically restored.

L298N, Perfect alternative.This product posing for sale, every large= 5 * 8 = 40Small pieces

Product Highlights:

1. Imported original professional motor drive chip, built-inLow conduction resistanceMOSSwitch tube,Heat is very small, no heat sink, small size, power,Is ideal for your battery-powered.

(L298N internal transistor switch, low efficiency, high heat, need to heat, bulky, the market is easy to burn the L298N, are not using the original chip, the product can be a perfect alternative.

2. Dual 1.5A * 2, the peak current to 2.5A, built-in thermal protection circuit, do not worry about the motor stall burned, the temperature automatically after the recovery.(Currently on the market of intelligent car voltage and current are in this range)

3. Small size, light weight, 0 standby current, your model is ideal for car

Product parameters:

1. Dual H-bridge motor drive, you can drive two DC motor or a 4-wire two-phase stepper motor;
2. Module supply voltage 2V-10V;

Precautions:

1.Reverse polarity of the positive and negative terminals of the power supply will cause damage to the circuit.

2.Output to the ground short circuit or output short circuit, as well as the case of motor stall, the chip will be thermal protection, but close to or over10VVoltage and peak current is much higher2.5AThe case will also cause the chip burned.
