Description
Module with popular L298N controller, which allows to control direction and speed of two DC motors. Thanks to ARK screw connectors, power supply and motors themselves can be easily connected by screwing wires with a screwdriver. Control signals are connected to popular goldpin connectors, allowing to connect the circuit to run boards, such as Arduino, using wires.
Pinouts
| PIN | DESCRIPTION |
|---|---|
| VMS | Supply voltage for motors from 5 V to 46 V. |
| 5V | Power supply of the logic part after the stabilizer – active after removing the 5V jumper. |
| GND | System ground |
| MOTOR A |
Motor A channel outputs. |
| MOTOR B |
Outputs of motor channel B. |
| ENA | PWM signal for speed control of motor A. |
| IN1, IN2 | Direction control of motor channel A |
| ENB | PWM signal for motor speed control B. |
| IN3, IN4 | Direction control of channel B |
L298 CONTROLLER TRUTH TABLE
| IN1 / IN3 | IN2 / IN4 | MOTOR OUTPUTS |
|---|---|---|
| status high |
status low state |
The motor turns clockwise at the maximum speed set by pwm (different from 0). |
| state low state |
state high |
The motor turns at the maximum speed set via pwm (different from 0) counterclockwise. |
| state low |
state low state |
When the high state is given to the PWM input – the motor is braked quickly (fast stop). |
| state high state |
state
high state |
When the high state is given to the PWM input – fast motor braking (fast stop). |
| state high |
state high state |
When the low state is given to the PWM input – free braking (soft stop). |
