โมดูลขับมอเตอร์ L298N motor drive board module DC stepper smar car robot กระแสสูงสุด 7A 160W

Product Highlights:

• Double H bridge, can drive two DC motors at the same time, single channel 7A current, high power;
• Wide voltage input 6.5V~27V;
• Signal optocoupler isolated input, can be directly controlled by IO port, free from interference;
• Under-voltage protection to prevent instantaneous high current from burning the module;
• High-power TVS and electrostatic discharge circuit, suppress transient interference pulse and static electricity, enhance EMC performance, product stability and reliability, industrial-grade design.

• The power supply voltage is 6.5V-27V, the power supply must not be reversed or exceed 27V, otherwise it may burn the module, it is recommended to connect a 15A fuse in series at the power input end.
• Dual-channel motor interface, each rated output current 7A, peak current 50A, motor interface must not be short-circuited, it is recommended to connect 10A fuse in series 。
• The control signal voltage is 3-6.5V, which are the enable signal and the forward and reverse control signal.
• Enable signal terminal (ENA) input PWM adjustable speed, PWM frequency range 0-10KHZ, PWM minimum pulse width 10us.
• Working temperature -25°C-80°C.
• Product size: 55*55*16mm (length, width and height).
• Mounting hole diameter: 3mm, pay attention to prevent the back circuit short circuit when installing, you can add an insulation pad or copper column to raise the circuit board 
• 8. Weight: 20 g.

Suitable for motor parameters:

For motors with a rated voltage of 24V, the rated power is 115W and below Or identify the rated current below 7A motor for a long time full work

For motors with a rated voltage of 12V, the rated power is 40W and below Or identify the rated current below 7A motor for a long time full work

Notes:

1 The driver power supply must not be reversed, it is recommended to connect a 15A fuse in series at the power interface, and the voltage should be between 6.5~27V. If the voltage is overvoltage, power-on may burn the drive module.

2. It is recommended that the rated output current of the power supply be more than 2 times the rated current of the motor, so as not to cause the power supply to provide the current required when the motor starts, causing the power supply voltage to drop, so that the power supply voltage cannot reach the input voltage required by the driver, so that the drive module performs undervoltage protection and turns off the output, resulting in the motor stalling phenomenon.

3. The motor interface must not be short-circuited, otherwise the drive module may be burned, it is recommended to connect a 10A fuse in series at the motor interface.

4. When switching forward and reverse, you need to brake more than 0.1S and then reverse, and cannot reverse when the motor has not stopped, otherwise the drive may be damaged.

5. When the drive module is powered off, do not directly or indirectly rotate the motor at high speed, otherwise the electromotive force generated by the motor may burn the drive module. If the application requires high-speed rotation of the motor when the drive module is powered down, it is recommended to connect a relay in series (NO and COM terminals in series) at the motor interface of the drive, and the relay coil is shared with the driver. In this way, when the power supply is lost, the relay will disconnect the drive from the motor.

6． Be careful not to get the driver wet, do not short-circuit the components on the driver board, and do not touch the pins and pads of the components on the board with your hands.
