Instructions for Use:

1. Power Supply: Ensure the module is powered by a stable 3.3V power supply. The module can draw up to 500mA during active transmission.
2. GPIO Configuration: Configure GPIO pins as required using your development environment. Some pins may have specific functions like SPI, I2C, or UART communication.
3. Programming Interface: Use USB-to-UART bridge boards for programming and debugging. Connect via TX/RX pins on the module.
4. Wi-Fi & Bluetooth Setup: Initialize Wi-Fi and Bluetooth functionalities through the provided libraries in the ESP-IDF or Arduino IDE.
5. Antenna Connection: For optimal performance, ensure the onboard PCB antenna has a clear path for signal transmission. External antennas can be connected if needed.
6. Software Development: Develop applications using ESP-IDF (Espressif IoT Development Framework) or Arduino IDE. Ensure you have the latest drivers and firmware updates installed.
7. Heat Dissipation: Consider heat dissipation solutions if operating under heavy load conditions. Proper ventilation or heatsinks may be necessary.
8. Environmental Conditions: Operate within recommended temperature and humidity ranges to avoid damage. Typically -40掳C to +125掳C for industrial grade.

For detailed specifications and advanced configurations, refer to the official Espressif documentation and datasheets.
