ESP-NOW fan control based on ESP8266 chip

Product Introduction: This product aims to control a fan using communication protocols such as Wi-Fi and ESP-NOW.
Issues encountered include:
1. Insufficient current, resulting in insufficient fan speed.
2. The panel is slightly larger than the PCB, requiring PCB size modification.
3. The 3D casing needs modification.
4. The AHT20 sensor is difficult to solder; replacing it with a temperature and humidity sensor is considered.
These issues will be addressed gradually.
Note:
The fan interface is incompatible; please contact the seller to have the correct female connector provided
