Detailed Product Description:

The ESP-WROOM-32 (30 pin) is a powerful and versatile IoT development board that has become a cornerstone for makers and engineers worldwide. At its core, this module is powered by the ESP32-D0WDQ6 chip, featuring a robust dual-core Tensilica LX6 processor that can be clocked up to an impressive 240MHz. This raw processing power, combined with 520KB of SRAM and 4MB of integrated flash memory, makes it capable of handling complex tasks from voice encoding to real-time data analysis.

What truly sets this board apart is its integrated wireless connectivity. It is a dual-mode solution with built-in Wi-Fi (802.11 b/g/n) and Bluetooth (v4.2 with BLE), allowing it to serve as a hub for a wide array of applications. Its low-power consumption is a game-changer for battery-powered devices, with a deep sleep mode that draws less than 5µA, perfect for long-term projects like remote sensors. The 30-pin configuration provides abundant GPIO pins and rich peripheral interfaces like I2C, SPI, and UART, making it easy to connect a variety of sensors and components.

Whether you're developing a smart home automation system, a wireless sensor network, or a complex robotic controller, the ESP-WROOM-32 offers unmatched flexibility and performance. It is easily programmable using the popular Arduino IDE, which simplifies the development process for both beginners and seasoned programmers. This IoT smart networking module is an essential tool for bringing your connected and intelligent project ideas to life.
