ESP32-S3-WROOM-1-N16
Overview
The ESP32-S3-WROOM-1-N16 is an Espressif S3-series wireless module that combines an ESP32-S3 SoC with 16 MB of onboard SPI flash for larger firmware and filesystem storage. It provides integrated 2.4 GHz Wi-Fi and Bluetooth Low Energy connectivity in a pre-certified module package. The module is intended for embedded IoT devices that need more flash for complex applications or local data storage.
Why Choose This Part
This module pairs the ESP32-S3 SoC with a larger 16 MB SPI flash, reducing constraints on firmware size, assets, and local storage. Using a pre-certified module lowers regulatory work and simplifies antenna design compared with discrete chip solutions. The ESP32-S3 family also has software ecosystem support (Espressif ESP-IDF, Arduino core) and community examples for common IoT and edge tasks.
Applications
Getting Started
Use Espressif ESP-IDF as the official SDK or the Arduino core for ESP32 for simpler sketches; PlatformIO also supports the S3. Typical development uses Espressif DevKit boards (for example the ESP32-S3-DevKitC series) or a module on a custom carrier board, and flashing is commonly done with esptool.py over the serial bootloader. Consult Espressif documentation for module pinout, recommended antenna and power layout, and partition table configuration when using large flash.
