Additional Information
The ESP32 Development Board (38-Pin) is a versatile development board built around the ESP-WROOM-32 module from Espressif System. It is designed to support modern embedded and wireless projects by combining a powerful processing unit with integrated connectivity features. With its well-organized pin layout and onboard components, the board is suitable for both rapid prototyping and structured development work.
This board includes a dual-core 32-bit processor, along with integrated Wi-Fi and Bluetooth, allowing seamless communication in connected applications. The onboard CP2102 USB-to-UART converter ensures stable and straightforward programming through a standard USB connection. Due to its balanced performance, low power requirements, and broad software compatibility, the ESP32 Development Board is widely used in IoT systems, automation solutions, robotics projects, and general embedded development.
When comparing the ESP32 to the Arduino, Atmel, or PIC, you'll find that the ESP32 Devkit V1 offers more pins, a faster processor, and superior overall performance.

Note:
There are three mutually exclusive ways to provide power to the board:
The ESP32 can be programmed using various platforms, such as the Espressif IDE, Thonny IDE, PlatformIO with Visual Studio Code, and the Arduino IDE. A quick search on Google will yield numerous online tutorials covering these platforms. Some notable examples include:
Once you have installed ESP Boards via the Board Manager of Arduino IDE, you can find various example projects, including Blink, Digital Read Serial, Analog Read Serial, Button, PWM, WiFI Web Server, WiFi Web Client, etc.
From the Arduino IDE, go to Tools > Board and select esp32 > ESP32 Dev Module. Once you have the ESP32 board chosen, go to File > Examples. Inside that folder, you will find various example sketches for different functionalities like WiFi, Bluetooth, Sensors, and more.

Yes, the ESP32 Development Board (CP2102 Chip, 38 Pin) supports both Bluetooth and Wi-Fi.

How exactly do I program it? I have purchased it and can't seem to have figured out how to configure my arduino IDE to compile a code for it. I may not have selected the correct board. None of the names seem to be explicitly referring to this board. Help would be appreciated.
