Overview

The ESP32-WROOM-32UE-N4 is a powerful WiFi and Bluetooth LE module featuring the dual-core Xtensa 32-bit LX6 microprocessor and 4MB of flash memory. It includes a U.FL connector for an external antenna, making it ideal for applications requiring specialized antenna placement or enclosures that block RF signals. This module supports a high data rate of 150Mbps and features extensive peripheral connectivity including 18 ADC channels and 26 GPIO pins.

Why Choose This Part

The inclusion of a U.FL connector allows for flexibility in RF design, enabling the use of external antennas to improve range or penetrate metal enclosures. Its dual-core processor allows for the separation of communication tasks and user application code, ensuring high performance even under heavy network loads.

Applications

Industrial IoT Gateways
Uses the U.FL connector to bridge internal circuitry to an external high-gain antenna for reliable connectivity in noisy environments.
Home Automation Hubs
Leverages concurrent Wi-Fi and Bluetooth LE to control smart devices while maintaining a cloud connection.
Connected Sensor Nodes
Utilizes the 12-bit ADC and low-power sleep modes for remote monitoring applications.
Audio Streaming Devices
Employs dual-core processing and I2S interfaces to handle wireless audio data processing.
