This module is based on L298N,
dual full bridge driver which 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.
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 is HIGH,
IN1 IN2 control OUT1 OUT2 When ENB is HIGH,
IN3 IN4 control OUT3 OUT4 Application:
1: driving stepper motor
