Enhanced RF Car PCB with ESP32-C3 – Version 2

This project is an improved second version of an RF-controlled car PCB featuring the ESP32-C3 microcontroller. In this version, a DC motor driver (L293D) has been added to control the car's two DC motors, significantly enhancing its functionality.

The circuit can be powered through the J1 terminal block (5V) or via the USB-C port (P1), providing flexibility in power options. It includes two buttons, BOOT and RESET, specifically for ESP32 operations.

Four 2N2222 transistors are used to convert the 3.3V logic from the ESP32-C3 to the 5V required by the L293D motor driver to ensure proper voltage level shifting.

The PCB features three LEDs for status indication:

• A red LED indicates when the circuit is powered on.
• A green LED is controlled by the ESP32-C3.
• A WS2812 addressable RGB LED, also managed by the ESP32-C3, for additional visual feedback.
• 
  

This project is ideal for students and electronics enthusiasts who are beginning their journey into the world of RF communication and microcontrollers. It offers a hands-on approach to learning about wireless control, embedded systems, and motor driver integration.
