ESP32-S3-WROOM-1-N16R8 is an Espressif Systems surface-mount wireless MCU module for connected embedded products. This exact N16R8 configuration combines 16 MB Quad-SPI flash with 8 MB Octal-SPI PSRAM and an on-board PCB antenna.

Key specifications Processor: dual-core Xtensa LX7, up to 240 MHz Wireless LAN: 2.4 GHz Wi-Fi, IEEE 802.11 b/g/n Bluetooth: Bluetooth 5 Low Energy (LE) Flash memory: 16 MB Quad-SPI PSRAM: 8 MB Octal-SPI Antenna: on-board PCB antenna Supply voltage: 3.0–3.6 V; 3.3 V typical Module dimensions: 18.0 × 25.5 × 3.1 mm Standard ambient operating range: −40°C to +65°C Development platform: ESP-IDF

Integration notes This is a bare solder-down module, not a development board. A suitable host PCB, regulated supply, antenna clearance and programming connections are required. The listing does not include a USB development board, headers, cables or other accessories. Consult the linked ESP32-S3-WROOM-1 / WROOM-1U family datasheet for the exact N16R8 memory configuration and reserved pins. Any higher-temperature use requires review of the datasheet's PSRAM ECC conditions and reduced usable memory.

Applications Suitable for integration into IoT sensors, industrial monitoring, connected appliances and embedded user interfaces. Application suitability depends on the complete host design.
