ESP32-S3-WROOM-1U-N8
Overview
The ESP32-S3-WROOM-1U-N8 is a powerful Wi-Fi and Bluetooth LE MCU module featuring the ESP32-S3 SoC and 8 MB of SPI flash. This specific variant includes an IPEX (U.FL) connector for an external antenna, making it ideal for applications requiring high-gain antennas or enclosure-mounted RF solutions.
Why Choose This Part
The module features a dual-core Xtensa LX7 processor with native USB support and AI acceleration capabilities. Its 8 MB of flash provides ample storage for large application codebases, while the IPEX connector allows for flexible antenna placement in metal or thick-walled enclosures.
Applications
Getting Started
Development is primarily done using the Espressif IoT Development Framework (ESP-IDF) or the Arduino core for ESP32. Hardware prototyping is best started with the ESP32-S3-DevKitC-1 development board series, and flash programming is handled via the integrated USB-to-Serial or native USB interface.
Dev Boards
Development boards and breakout modules featuring the ESP32-S3-WROOM-1U-N8 or compatible chips — ready to use for prototyping.
