4WD Robot Car

4WD Robot Car uses SparkFun RedBoard Qwiic as the main control board and is combined with L298N motor drive board, forming a powerful intelligent mobile device. As for L298N motor drive board, since it provides stable power output and flexible steering control, it is responsible for driving wheels.

L298n Motor Driver

That’s where the L298N motor driver module comes in. It acts as a bridge between your low-power Arduino and your high-power motors. You send small control signals from the Arduino, and the L298N safely handles the higher current required by the Motor DC.
