Step 1: Understanding the Components

• The main components for this project are the ESP32-S3 Mini, LEDs, PMOS transistor, diode, voltage regulator, and a battery. These components will help in creating a custom PCB with WLED software control.

Step 2: Powering the LEDs

• The LEDs can be powered either directly from the USB or battery source, or from an external power supply. Ensure the LEDs receive the required voltage for proper functioning.

Step 3: Implementing the Power Path Circuit

• Create a power path circuit using a PMOS transistor, diode, and voltage regulator to manage the power source between USB and battery. This circuit ensures a smooth power supply to the system.

Step 4: Assembling the PCB

• Design and assemble the PCB layout incorporating the components mentioned above. Ensure proper connections and soldering for a functional circuit.

Step 5: Testing the PCB

• Connect the PCB to a power source and test the functionality. Check if the LEDs light up as expected and if the power path circuit works correctly.

Step 6: Programming the ESP32

• Program the ESP32 with the WLED software to control the LEDs' patterns and effects. Follow the instructions provided by the WLED software for setting up the desired lighting effects.

Step 7: Adding Indicator LEDs

• Include indicator LEDs for battery charging status if required. These LEDs can provide visual feedback on the battery's charging status.

Step 8: Final Touches

• Consider adding a base for the custom PCB for a polished look. You can experiment with different materials for the base to enhance the overall aesthetic appeal of the project.

Step 9: Troubleshooting and Refinement

• Test the PCB thoroughly for any issues or malfunctions. Troubleshoot and refine the circuit as needed to ensure optimal performance.

Step 10: Share and Seek Feedback

• Share your custom ESP32 PCB project with others and seek feedback on platforms like YouTube or forums. Engage with the community to gather insights and improve your skills further.

By following these steps, you can create a custom ESP32 PCB with WLED software control, powering LEDs with a sophisticated power path circuit, and adding unique features like indicator LEDs for battery status. Enjoy experimenting and showcasing your creation to the world!
