WLED controller

Project Introduction
This project is an RGB controller based on ESP32, capable of controlling common LED strip
projects such as 5V and 12V programmable LED strips and RGBWW
. This project is based on hardware developed using the open-source software WLED (WLED open-source address: https://github.com/Aircoookie/WLED). For achievable functions, please refer to the open-source page; this section only describes the hardware design features.
Project Parameters

This design uses USB power supply, with a CH224K to induce 12V (requires a PD3.0 charger). A toggle switch allows selection of 5V and 12V power supply for the LED strip (do not toggle while powered on).
The main controller uses the ESP32-WROOM-32E-N4 module with an onboard CH340C. WLED provides web-based programming. Connect the device directly to a computer via USB, press and hold the IO0 button, then press the EN button to enter programming mode on the ESP32, and click "install" on the webpage to complete the firmware programming.
An SN74HC244 is used for level conversion, converting the 3.3V output from the ESP32 IO to 5V.
The onboard silicon microphone enables
two-channel programmable LED strip output and five-channel PWM output.

The software code
can be directly programmed with WLED open-source code or Chinese code compiled based on WLED.
Note:

The CH224K decoy circuit is unverified because all available PD fast chargers have a 12V output disabled.
The silicon microphone package cannot be manually soldered .
The programmable LED strip output IO pins are IO25 and IO33; onboard testing uses IO2. A
