Product Overview
ESP32-S3-WROOM-1-N8 is an Espressif SMD wireless module built around the ESP32-S3 MCU and an integrated PCB antenna. It combines 2.4 GHz Wi-Fi and Bluetooth Low Energy connectivity with embedded MCU processing, reducing the RF-component and antenna-design burden compared with a bare wireless SoC.
The exact N8 suffix identifies 8 MB of Quad SPI Flash with no integrated PSRAM. That distinction matters for firmware images, graphics/data buffering and application frameworks: designs that require external PSRAM should select an appropriate memory variant rather than assuming all ESP32-S3-WROOM-1 modules have the same memory configuration.

Functional Highlights
N8 is a memory configuration, not just a stocking suffix
The exact module contains 8 MB Flash and no PSRAM. Firmware architecture and memory-intensive workloads should be checked against that configuration before the module is frozen into the BOM.
Integrated antenna simplifies RF implementation but does not eliminate RF layout rules
The PCB antenna is part of the module, but the host PCB must still respect Espressif’s antenna keep-out, placement and ground guidance to preserve RF performance.
Applications / Application Fit
- Connected sensors and gateways
- Wi-Fi/BLE control panels and human-machine interfaces
- USB-enabled wireless embedded devices
- IoT nodes requiring an integrated module form factor
Design Considerations
Respect the antenna keep-out region and module placement rules; nearby copper, enclosure metal or batteries can degrade RF performance.
Use a 3.3 V rail with adequate transient-current margin and local decoupling for radio activity.
Choose a PSRAM-equipped variant if the application’s frame buffers or data sets exceed the practical internal-memory budget.
