L298N V2.0

This circuit diagram shows a motor driver board using an L298N dual H-bridge motor controller chip. It includes connections for 4 DC motors or other devices to be controlled by 4 input pins and powered by a 12V supply. Pulse width modulation (PWM) signals can be input on two pins to control the speed of two of the motors. Resistors and LEDs are used to indicate the status of outputs.
