Description
L298N is a dual H-bridge monolitic high power integrated circuit designed to accept standard TTL levels for control.
Can be used to control relays, solenoids, DC and stepper motors.
Each bridge can be activated or deactivated individually by using the ENA, ENB pins.
The module contains a voltage stabiliser (5V) which allows it to work at high voltages.
Specifications:
-Operating voltage: up to 40V
-Operating current: up to 3A (25W in total)
-Low saturation current
-Overheating protection
-Can operate 2 motors simultaneously
- High noise immunity: "0" logic level up to 1.5V
- Voltage regulator (78M05). This is enabled from the JP8 jumper. To avoid burning this circuit use an external 5V power source when the motor voltage is over 12V (and disable JP8).
How to control a DC motor:
| ENA | IN1 | IN2 | State of the DC motor (A) |
| 0 | X | X | Stop |
| 1 | 0 | 0 | Break |
| 1 | 0 | 1 | Clockwise rotation |
| 1 | 1 | 0 | Counterclockwise rotation |
| 1 | 1 | 1 | Break |
To control the motor speed, the ENA pin must be connected to a PWM pin on the Arduino.
