Description
The module with the popular L298N driver IC allows you to control the direction and speed of two DC motors. Thanks to the screw connectors, ARK power and engines can be easily connected by fastening the wires using a screwdriver. The control signals were output into popular gold pin connectors that allow you to combine the system with commissioning plates, for example, with Arduino using wires.
Leads
| PIN | DESCRIPTION |
|---|
| +12V | The voltage of the motor’s power supply. |
| +5V | The power of the theological part with the regulator – is active after you remove the jumper 5V. |
| GND | The weight of the system |
OUT1, OUT2
| The channel outputs of engine A. |
| OUT3, OUT4 | The channel outputs of engine B. |
| ENA | PWM signal to control the rotational speed of the engine A. By default, it is connected to 5 V by jumper -which means that the engine works with the maximum speed. |
| IN1, IN2 | Control of channel A direction |
| ENB | PWM signal to control the rotation speed of motor B. By default, connected to the 5 V by jumper – it means that the engine works with maximum speed. |
| IN3, IN4 | Direction control of channel B |
The truth table of driver L298
| IN1 / IN3 | IN2 / IN4 | THE OUTPUTS OF THE ENGINES |
|---|
| high state | low state | The motor rotates with the maximum given speed using PWM (different from 0) in a clockwise direction. |
| low state | high state | The motor rotates at the maximum given speed using PWM (not equal to 0) in a counterclockwise direction. |
| low state | low state | When indicated high state at the PWM input – fast braking of the motors (fast stop). |
| high state | high state | When indicated high state at the PWM input – fast braking of the motors (fast stop). |
| high state | high state | When indicated low state at the PWM input – free braking (soft stop). |
