Overview

The ESP32-WROOM-32UE-N16 is a high-performance WiFi and Bluetooth dual-mode module featuring 16MB of flash memory and a U.FL connector for external antenna attachment. It is powered by the dual-core Xtensa 32-bit LX6 microprocessor operating at up to 240MHz, offering a robust solution for connected applications requiring significant storage and flexible RF design.

Why Choose This Part

This module provides an expansive 16MB of flash memory, which is ideal for large firmware images and Over-the-Air (OTA) updates. The U.FL connector allows engineers to bypass the limitations of PCB antennas by using external antennas for better range or specific mounting requirements.

Applications

Industrial IoT Gateways
Uses the 16MB flash for local data logging and the U.FL connector for external high-gain antennas in metal enclosures.
Smart Home Hubs
Supports simultaneous WiFi and Bluetooth LE connections to bridge local sensor networks to the cloud.
Service Robotics
The dual-core architecture allows one core to handle real-time motor control or sensor processing while the other manages network stacks.
Asset Tracking
Utilizes the 2.4GHz transceiver and low power modes for monitoring equipment status in large facilities.
