Espressif ESP32-WROVER-IE-N4R8 Wi-Fi + Bluetooth Module

Description

The ESP32-WROVER-IE-N4R8 is a robust, industrial-grade wireless module built around Espressif’s flagship ESP32-D0WD dual-core Xtensa LX6 microcontroller. It integrates a complete 2.4 GHz RF system with support for 802.11 b/g/n Wi-Fi, Bluetooth Classic, and Bluetooth Low Energy 4.2, making it a cornerstone for connected devices.

Its key differentiator is the substantial 8MB of integrated PSRAM, which provides ample memory for audio buffers, graphics processing, and complex application data, enabling use cases like MP3 decoding and voice encoding that are beyond the scope of standard ESP32 modules. The module is supplied with 4MB of flash for firmware storage. The inclusion of an external antenna connector (IPEX) allows system designers to optimize RF performance for specific enclosure and placement requirements.
