Eye of God Lite

I. Functions (Please see the demonstration video for detailed functions)
1. Press the power button to turn on the device and enter the main interface (and automatically synchronize the time).
2. Long press the settings button on the main interface to enter settings.
3. Functions in God's Eye mode.
4. Functions in music mode. 5. Ai Ayaka function: Due to my computer not having an Nvidia card, development is temporarily suspended; BBZD is a small cooling and heating fan that I will make in the future. In BBZD mode, BBZD can be controlled through God's Eye. This function will be implemented later.
6. Infrared remote control and learning mode (not shown in Figure 1): The air conditioner can be turned on and off remotely through God's Eye. This function will be implemented later.
7. Ambient temperature detection mode (not shown in Figure 1): Displays the real-time ambient temperature. This function will be implemented later.
II. Hardware Design (BOM is based on the circuit diagram. The automatically generated BOM at the end of the document may have bugs)
Motherboard: Integrates ESP32, screen, 32G surface mount SD card, DS2321 clock, buttons & single-button power on/off, lithium battery charging & buck & power detection, USB to serial port, USB card reader, infrared transceiver, speaker, temperature sensor, power indicator, etc.
Note: GPIO2 needs to be pulled low when uploading the program
. After simple testing, the hardware works normally. III. Shell & Structure
God's Eye The outer shell of the eye is shown below.
The cover of the Eye of God's outer shell, manufactured using 3D printing, is shown below. The groove in the button area is for holding the membrane panel. Because the button length is insufficient, it needs to be raised, so the following button pads were designed (4 need to be 3D printed).
The button panel in the cover area of ​​the Eye of God's outer shell is shown below. The area in the upper left square is the actual button panel. Because the minimum printable size of the LCSC panel is 200*300, some images were added to fill the blank areas to avoid waste. Please approve...
