ESP32-WROOM-32E-N8R2
Overview
ESP32-WROOM-32E-N8R2 is an Espressif wireless module built around the ESP32-D0WD-V3 SoC. It combines a dual-core microcontroller with integrated Wi-Fi and Bluetooth in a shielded module format for embedded designs. The N8R2 variant indicates an on-module flash and PSRAM configuration, making it useful for connected products that need more memory headroom.
Why Choose This Part
This module is attractive when you want Espressif's ESP32 ecosystem in a compact, pre-certified module form factor. The WROOM package simplifies RF design compared with building an ESP32 design from the bare SoC, and the N8R2 memory configuration gives more room for firmware, networking stacks, and application buffers. It is a strong fit for cost-sensitive connected products that still need solid tooling and broad community support.
Applications
Getting Started
Use an ESP32 development board or a carrier board with a USB-to-UART interface for initial bring-up. Espressif's ESP-IDF is the primary development framework, and Arduino core support is also widely used for faster prototyping. For RF and power integrity, follow Espressif's reference designs closely, especially for antenna keepout, decoupling, and supply current peaks during Wi-Fi transmission.
Dev Boards
Development boards and breakout modules featuring the ESP32-WROOM-32E-N8R2 or compatible chips — ready to use for prototyping.
