Overview

The ESP32-WROVER-E-N16R8 is a high-performance WiFi and Bluetooth v4.2 +EDR module powered by the dual-core Xtensa 32-bit LX6 microprocessor. It features a massive 16 MB of flash memory and 8 MB of PSRAM, making it suitable for memory-intensive IoT applications that require significant data buffering or complex firmware. The module includes an integrated PCB trace antenna and is certified for rapid integration into commercial products.

Why Choose This Part

This module provides a significant memory headroom with 16 MB flash and 8 MB PSRAM, which is essential for Over-the-Air (OTA) updates of large firmware images and complex applications. It offers high output power of 20.5dBm for reliable 2.4GHz communication and supports 18 ADC channels for extensive analog sensor interfacing.

Applications

IoT Gateway
Acting as a bridge between local Bluetooth LE sensor networks and cloud services via WiFi, utilizing the large PSRAM for message queuing.
Voice Recognition and Audio Streaming
Processing audio data through I2S and utilizing the dual-core processor for SBC or CVSD decoding.
Smart Home Hub
Managing multiple concurrent connections and hosting local web servers for device configuration and monitoring.
Industrial Data Logger
Collecting sensor data via ADC and I2C and storing large datasets locally in flash before periodic uploads.
