Motor driver module L298N Dual H-Bridge with current sensing
Product information:
The L298N Dual H-Bridge Motor Driver is a motor driver board that can be used to drive two robot motors. It uses the popular L298N Dual H-Bridge Motor Driver chip and is powerful enough to drive motors from 5-35 volts with up to 2 amps per channel. The flexible digital input controls ensure that each motor is completely independent with full control over speed direction and braking action.
This board provides a convenient 5V regulator that can be used to power other circuits, such as your robotics microcontroller. The modular design can be easily adapted to a wide range of robotics controllers, including the popular Arduino family.
