Description
The module with the popular L298N driver that 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 goldpin connectors that allows you to combine the system with commissioning plates, for example, with Arduino using wires.
| For Arduino users, available is a sample program simplifying maintenance of the module. |
Leads
| Pin | Description |
|---|---|
| +12V | The voltage of the motors power supply. |
| +5V | The power of thelogical part with the regulator - active after you remove the jumper 5V. |
| GND | The weight of the system |
| OUT1, OUT2 |
The channel outputs of the engine A. |
| OUT3, OUT4 | The channel outputs of the engine B. |
| ENA | PWM signal to control the rotational speed of the engine A. By default, it is connected to 5 V by jumper -it 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 the motor B. By default, connected to the 5 V by jumper - it means thatthe engine works with maximum speed. |
| IN3, IN4 | Direction control of channel B |

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). |
