Multifunctional desktop clock based on ESP-WROOM-32

* 1. Project Function Introduction This project uses the ESP-WROOM-32 as the main control chip and a 1.8-inch TFT screen for display. The PCB size is 80mm*50mm. The power supply uses the SY8088, a DC/DC regulator capable of providing up to 1A of output current. Power charging and discharging management uses the TP4057. An interface for a JW01 gas detection module is reserved for future upgrades. * 2. Open Source License MIT License *3.
