Maximum Power: 25W
Weight: 30g
External dimensions: 43 * 43 * 27mm
Product Features:
This module uses ST's L298N chip as the main driver, driving ability, low heat, strong anti-interference ability.
This module can use the built-in 78M05 to take power by driving the power section, but in order to avoid damage to the regulator chip, when use is greater than the drive voltage of 12V, use an external 5V logic supply.
The module uses a large-capacity filter capacitors, drain diode can improve reliability.
The cargo module audience, photographed you, thank you.
Driver module range of applications
The L298N is the ST Company production of a high-voltage, high-current motor driver chips. The chip uses a 15-pin package. The main features are: high operating voltage, the maximum operating voltage of up to 46V; Output current instantaneous peak current up to 3A continuous operating current of 2A; rated power of 25W. Contains two H-bridge high voltage and high current full-bridge driver can be used to drive a DC motor and stepper motor, relay coil inductive load; using standard logic level signal control; having two enable control end allow or prohibit the work has a logic device power supply input terminal, in the case regardless of the input signal affect the internal logic circuit portion to operate at a low voltage; can be an external sense resistor, the amount of change in feedback to the control circuit. The L298N chip drive motor, the chip can drive two-phase stepper motors or four-phase stepper motor can drive two DC motors.
Port Function Chart
This module integrates a built-in 5V power supply. When you drive voltage of 7V-35V can onboard 5V logic supply, do not input voltage when using onboard 5V power supply, the +5 V power supply interface, but leads to 5V voltage for external use
When ENA so IN1 IN2 control OUT1 OUT2
When ENB so IN3 IN4 control OUT3 OUT4
Application examples:
1: drive stepper motor
Drive ordinary 4-wire 2-phase motor connection, as shown
Enable ENA ENB
From IN1 - IN4 enter the following drive timing, you can control the speed and direction of the stepper motor
