ESP32-WROVER-B-N8R8
Overview
The ESP32-WROVER-B-N8R8 is a high-performance 2.4GHz Wi-Fi and Bluetooth LE module powered by the dual-core Xtensa LX6 MCU. This specific variant is distinguished by its 8MB of integrated PSRAM and 8MB of flash, making it suitable for memory-intensive applications that exceed the standard internal SRAM capacity.
Why Choose This Part
The module offers a significant memory advantage with 8MB of external PSRAM, allowing for larger heap allocations than standard ESP32 modules. Its dual-core architecture enables the separation of protocol stack management and user application code for improved deterministic performance at clock speeds up to 240MHz.
Applications
Key Specifications
Getting Started
Engineers typically develop for this module using the ESP-IDF (IoT Development Framework) or the Arduino IDE with the ESP32 core. For hardware evaluation, the ESP32-DevKitC series supports these modules, requiring the 'PSRAM' feature to be enabled in the project configuration (menuconfig) to utilize the additional 8MB of RAM.
