Design a complete standalone L298N dual-channel H-bridge motor driver circuit.

Use the L298N motor driver IC.

The circuit must be complete and suitable for later import into KiCad and integration into a larger ESP32 PCB.

POWER INPUT:
- 12V DC motor supply
- GND
- Logic supply for L298N
- Clearly label VMOTOR and GND

MOTOR CHANNEL A:
- OUT1
- OUT2
- ENA
- IN1
- IN2

MOTOR CHANNEL B:
- OUT3
- OUT4
- ENB
- IN3
- IN4

Add screw terminal connectors for:
- 12V power input
- Motor A
- Motor B

Add a separate logic-control header with:
- ENA
- IN1
- IN2
- IN3
- IN4
- ENB
- GND
- 5V logic

PROTECTION:
Add flyback protection diodes for both H-bridge channels according to the L298N datasheet/reference design.

POWER FILTERING:
Add appropriate bulk electrolytic capacitors on the motor supply.

Add ceramic decoupling capacitors close to the L298N supply pins.

Add a 5V supply/logic section according to the L298N datasheet.

Add a power indicator LED with a suitable current-limiting resistor.

THERMAL:
Provide the L298N in a package suitable for heatsinking.
Provide adequate copper area around the thermal ground/tab connection according to the datasheet.

LABELS:
Clearly label all external connections:
12V
5V
GND
ENA
IN1
IN2
IN3
IN4
ENB

DESIGN REQUIREMENTS:
- Follow the L298N datasheet/reference application circuit.
- Do not invent component connections.
- Use appropriate component values based on the datasheet.
- Keep motor-current paths short and wide.
- Keep logic signals separated from high-current motor paths.
- Make the schematic clean and easy to understand.
- Use standard through-hole components where practical.
- Do not include ESP32, BME680, OLED, sensors or other circuits.
- This is ONLY the complete L298N dual-channel motor-driver circuit.

Before completing the design, verify the power, ground, enable, input, output and protection connections against the L298N datasheet.
