The L298 chip is a brand new genuine chip. The SMD aluminum electrolysis uses two 35V 220UF high voltage and high capacity capacitors, while the imitation module uses a refurbished 2 hand chip, 35V 100UF and 10V 100UF low voltage and low capacity capacitors.
Features:

★ This module uses ST’s L298N as the main driving chip, which has the characteristics of strong driving ability, low heat generation and strong anti-interference ability.

★ This module can use the built-in 78M05 to get power through the drive power supply part, but in order to avoid damage to the voltage regulator chip, when using a drive voltage greater than 12V, please use an external 5V logic power supply.

Precautions:

1. When your drive voltage (marked as 12V input in the above figure, the actual acceptable input range is 7-12V) is 7V-12V, you can enable the onboard 5V logic power supply, when using the onboard 5V power supply , +5V in the interface
Do not input voltage for power supply, but you can draw 5V voltage for external use. (This is a regular application!)

2. When the driving voltage is higher than 12V, less than or equal to 24V (the chip manual suggests that it can support up to 35V, but according to the

It is very remarkable that 298 conservative application of maximum voltage support up to 24V has been verified! ), for example, to drive the rated voltage to

18V motor. First, you must remove the jumper cap of the onboard 5V output enable. Then connect 5V outside the 5V output port

5V enable is a control signal with a level of 5V. When this signal input is valid and the power supply in the motor drive module is normal, the motor drive module outputs current. Otherwise, even if the power supply is normal, there is no current on the motor.
The voltage supplies power to the internal logic circuit of L298N. (This is an unconventional application of high-voltage drive!)

The control logic of the stepper motor is as follows, where A, B, C, and D are the four coils of the stepper motor. A 1 indicates that there is current passing, and a 0 indicates that no current flows. The coil connection diagram is shown in the following figure (taking a four-phase stepper motor as an example)

Product parameters:

1. The power supply voltage is 6.5V-27V, the power supply must not be reversed or exceed 27V, otherwise the module may be burned out, it is recommended to connect a 15A fuse in series with the power input.

2. Dual-channel motor interface, rated output current of each channel is 7A, peak current is 50A, motor interface must not be short-circuited, it is recommended to connect 10A fuse in series.

Suitable motor parameters:

For motors with a rated voltage of 24V, it is suitable to mark the rated power of 115W or less or the rated current of 7A or less.

For motors with a rated voltage of 12V, it is suitable to mark motors with rated power of 40W or less or motors with rated current of 7A or less to work at full capacity for a long time.

Precautions:
1. The driver power supply must not be reversed. It is recommended to connect a 15A fuse in series at the power supply interface, and the voltage should be between 6.5 and 27V. If the voltage is overvoltage, the drive module may be burned when the power is turned on.

2. It is recommended that the rated output current of the power supply is more than twice the rated current of the motor, so as not to cause the power supply to fail to supply the current required when the motor is started, causing the power supply voltage to drop, so that the power supply voltage does not reach the input voltage required by the driver, so that the drive module performs undervoltage protection. Interruption of the output causes the motor to stall.

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 between forward and reverse rotation, the brake must be braked for more than 0.1S before reverse rotation. It cannot be reversed when the motor has not stopped, otherwise the driver 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 off, it is recommended to connect a relay (NO and COM terminals in series) to the motor interface of the drive, and the relay coil and the drive share the same power supply. In this way, when the power supply is powered off, the relay will disconnect the drive from the motor.

6. Note that the driver should not get 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
