Overview

The ESP32-WROVER-E-N4R8 is a high-performance Wi-Fi and Bluetooth LE module powered by the dual-core Xtensa LX6 32-bit processor running up to 240MHz. It features an integrated PCB trace antenna and includes 4MB of SPI flash alongside 8MB of external pseudo-static RAM (PSRAM) to support memory-intensive applications.

Why Choose This Part

This module provides a massive 8MB of SRAM, making it suitable for applications that exceed the internal 520KB RAM limits of standard ESP32 modules. Its high output power of 20.5dBm and sensitivity of -98dBm ensure robust wireless range and reliable connectivity in crowded 2.4GHz environments.

Applications

High-Resolution Audio Streaming
Utilizes the 8MB PSRAM and I2S interface for buffering and processing high-quality audio over Wi-Fi or Bluetooth.
IoT Edge Gateways
Acts as a bridge between local Bluetooth LE sensors and cloud platforms using its 802.11b/g/n connectivity.
Smart Home Hubs
Serves as a central controller using its 24 GPIOs to interface with touch sensors, PWM-driven lighting, and motor controls.
Industrial Monitoring
Leverages the 18-channel ADC and built-in pulse counter to monitor machinery sensors and report data over a secure wireless link.

Getting Started

Begin development using the Espressif IoT Development Framework (ESP-IDF) or the Arduino IDE with the ESP32 core. For hardware evaluation, use an ESP32-DevKitC or similar development board that supports WROVER modules to access the expanded PSRAM. Ensure your power supply can handle peak currents of 350mA during Wi-Fi transmission.
