Power Supply: Ensure the operating voltage is between 3.0V and 3.6V. Use an appropriate power supply or battery.
Programming: Use a USB-to-UART bridge for programming. The module supports flashing via the serial port using tools like ESPTOOL.
WiFi Setup: Configure Wi-Fi settings through the ESP-IDF or Arduino IDE. Connect to networks using standard Wi-Fi protocols.
Bluetooth Configuration: Utilize the Bluetooth stack provided by the ESP-IDF to configure classic Bluetooth or BLE functionalities.
Pin Configuration: Refer to the pinout diagram in the datasheet to configure GPIOs as needed. Be cautious with pins that share functions (e.g., SPI, I2C).
Deep Sleep Mode: Implement deep sleep for low-power applications. Configure wake-up sources such as GPIO changes or timer events.
Peripheral Interfaces: Initialize and configure peripherals like UART, SPI, I2C, I2S, and CAN according to your application needs.
Sensor Integration: Use built-in sensors (temperature, hall effect) directly in your code for monitoring purposes.
Development Environment: Choose a development environment like ESP-IDF for more advanced features or Arduino IDE for ease of use.
Documentation and Support: Always refer to the official Espressif documentation for detailed information and troubleshooting tips.
