ESP32-WROOM-32
Overview
The ESP32-WROOM-32 is a powerful, generic Wi-Fi and Bluetooth LE module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks. At its core is the ESP32-D0WDQ6 chip, designed to be scalable and adaptive with dual CPU cores that can be individually controlled.
Why Choose This Part
The module offers a versatile combination of Wi-Fi, Classic Bluetooth, and Bluetooth Low Energy, ensuring compatibility across diverse wireless ecosystems. Its dual-core Tensilica LX6 architecture allows for dedicated handling of the networking stack on one core while the application logic runs on the second, preventing timing jitter.
Applications
Getting Started
Developers can use the official Espressif IoT Development Framework (ESP-IDF) or the popular Arduino core for rapid prototyping. To begin hardware evaluation, the ESP32-DevKitC-1 development board is recommended as it breaks out all module pins to breadboard-friendly headers and includes a USB-to-UART bridge.
Dev Boards
Development boards and breakout modules featuring the ESP32-WROOM-32 or compatible chips — ready to use for prototyping.
