EasyMatrix Mini Pixel Clock

This project is based on the "Step-by-Step Replica of the EasyMatrix Pixel Clock" tutorial by Bilibili UP master @大聪明的二手脑袋, and incorporates suggestions from netizens. All hardware has been redesigned, and new commonly used hardware functions have been added. The PCB size has been reduced to 26x98mm. The new hardware functions are as follows: 1. Buzzer function (GPIO pins need to be pulled low to eliminate noise; the program is not yet adjusted). 2. Reserved power supply for AMS1117-3.3 (it's rumored that the core board has an onboard 3.3V). LDOs are prone to burning out, so one is reserved. 3. Onboard MAX9814ETD audio amplifier circuit (software configurable mode) 4. Add two Type-C interfaces to adapt to different cable directions (can achieve up, down, left, and right cable output directions for 90-degree plugs, supports power control) 5. Reserved high-precision DS3231 clock chip (used to optimize core heat generation during continuous WiFi operation or to achieve a completely offline clock, not yet adjusted in software) 6. Reserved AHT20 temperature and humidity sensor (affected by heat generation, the casing is insulated, not yet adjusted in software) 7. 5 buttons, one of which supports power control and customization (4 buttons + 1 multi-function button (only on, not yet adjusted in software)) 8. Onboard surface-mount photodiode (used to sense ambient light intensity and adjust brightness) 9. Core board debugging interface has been reserved (used for programming and debugging, does not support power control)
Warm reminder: This project is advanced content. Resistor and capacitor components use 0402 package to reduce size.
