Product features:

This module USES L298N as the main drive chip, with strong driving ability, low heat and strong anti-interference ability.

Through this module can use the built-in 78 m05 drive power supply parts of their work, but in order to avoid the voltage regulator chip damage, when using the driving voltage is greater than 12 v, please use the external power supply 5 v logic.

This module USES a large capacity filter capacitance, a continuation protection diode, can improve reliability.

Notes:

1. When you are driving voltage (above logo for the 12 v input, can actually accept input range is 7 to 12 v) for 7 v to 12 v, can make to onboard power supply 5 v logic, when using the onboard after 5 v power supply, interface of + 5 v

The power supply does not input voltage, but can yield 5V voltage for external use.

2. When the driving voltage is higher than 12V, it is less than or equal to 24V

(the chip manual proposes to support 35V, but according to the book

When the maximum voltage is applied to the maximum voltage of 298 conservative applications to 24V, for example, the motor with a rated voltage of 18V shall be driven.

You must first remove the board 5V output to enable the jumper cap. Then 5V is accessed outside the 5V output port

The 5V enables the power to be a control signal with a level of 5V. When the signal input is valid, and when the power supply is normal in the motor drive module, the motor drive module outputs the current. Otherwise, even if the power supply is normal, there is no current on the motor.

Voltage to L298N internal logic circuit power supply. (this is a high-pressure, unconventional app!)

Product Highlights:

Imported original professional motor-driven chip, built-in low-resistance MOS switch, low heat, no heat sink, small size, power, your battery is ideal for power supply.

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

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

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

Precautions:

Positive and negative power supply reversed will certainly cause circuit damage.

Output short circuit to the ground or output short circuit, and the motor stall case, the chip will be thermal protection, but close to or exceed 10V voltage and peak current of more than 2.5A cases will also cause the chip burned.

Stepper motors are usually defined with step angle or step parameters. The general motor is divided into 200 steps, that is, the step angle is 1.8 degrees. EasyDriver has step subdivision function. This driver board is subdivided. For the 8 subdivision, which is to subdivide each step of the motor into 8 small steps, it can get more precise control, which means that EasyDriver needs 1600 steps to complete a complete 360 degree rotation.

Ms1 and ms2 are logic input ports for stepping motor subdivision resolution selection;
Dir is the selection port for the motor running direction;
Reset is used to reset the initial value of the chip and mask all external outputs;
Step is a pulse input port;
Out1a, out1b, out2a, out2b are two pairs of output ports of the h-bridge;
Enable is the enable terminal;
Sleep is a sleep mode;
Sense1 and sense2 are current detecting resistors of the h-bridge;
Ref is the reference voltage;
Gnd is logical ground and power ground;

Rc1 and rc2 are the fixed-time analog input of the h-bridge.

A3967slb is a pwm constant current control micro-stepping drive two-phase stepper motor dedicated driver produced by Allegro Company of the United States. It can work up to 30v and drive current up to 750ma. One a3967slb can drive a two-phase stepper motor, which can realize 8 subdivision drive. The pwm current control circuit inside the chip can be set to three current decay modes by slow, fast, and mixed voltages applied to pfd. If the voltage at the pfd terminal is higher than 0.6vdd, the slow decay mode is selected. If it is lower than 0.21vdd, the fast decay mode is selected. In between is a mixed attenuation mode. In addition, the a3967slb also provides comprehensive protection measures, including suppression of transient voltage, overheat protection, protection against current through, under voltage self-locking and other functions.

There is no need to add other interface circuits between the a3967slb and the microprocessor. The chip adopts the easystepper interface and reduces the number of 8 control lines by 2 (step and direction). Simply input the pulse that controls the stepper motor. The embedded converter allows control of the stepper motor.

A3967slb also needs some resistors and capacitors to adjust its operating parameters, the whole drive circuit is very simple
