What are the key features of ESP32-S3-WROOM-1-N16R8?

Dual-core 32-bit Xtensa LX7 MCU clocked up to 240 MHz with vector instructions for AI inference
16 MB Quad SPI flash and 8 MB Octal PSRAM in-package — no external memory required for large RTOS firmware
Integrated 2.4 GHz Wi-Fi 4 (802.11 b/g/n) and Bluetooth 5 (LE) with on-module PCB antenna
45 programmable GPIOs supporting SPI, I2S, I2C, UART, RMT, USB-OTG, LCD, camera and SDMMC interfaces
3.0 V to 3.6 V single-supply operation, surface-mount LGA package, RoHS compliant and lead-free
AEC-Q100-style -40 °C to +85 °C operating range with peak reflow up to 250 °C

What is ESP32-S3-WROOM-1-N16R8 used for?

Used in smart-home gateways, voice-controlled appliances, industrial IoT sensor hubs, and AI-at-the-edge designs that need both wireless connectivity and modest neural-network inference. The large PSRAM and flash budget makes the N16R8 variant a fit for camera streaming, on-device wake-word detection, and ESP-IDF projects with extensive third-party component graphs.

Frequently Asked Questions

What is the difference between ESP32-S3-WROOM-1-N16R8 and the base N4 / N8 variants?

The -N16R8 suffix denotes 16 MB Quad SPI flash and 8 MB Octal PSRAM in the same module footprint, versus 4 MB or 8 MB flash and no PSRAM in cheaper variants. Choose -N16R8 when your firmware exceeds 4 MB, you need a large file system, or you stream camera or audio buffers that benefit from PSRAM.

Is ESP32-S3-WROOM-1-N16R8 RoHS compliant and lead-free?

Yes. The module is RoHS compliant, lead-free (Pb-free), and qualifies for standard surface-mount reflow up to 250 °C peak per JESD-30. It uses an LGA / SMD module body with PCB antenna and meets MSL handling requirements for production reflow.

What is the operating voltage and temperature range of ESP32-S3-WROOM-1-N16R8?

The module accepts a single 3.0 V to 3.6 V supply (3.3 V nominal) and is rated for an industrial -40 °C to +85 °C ambient. Peak Wi-Fi transmit current can reach 500 mA, so size your LDO or buck regulator with at least 1 A headroom and follow the Espressif PCB layout guide for the antenna keepout area.

Does ESP32-S3-WROOM-1-N16R8 support USB and AI workloads?

Yes. The S3 silicon adds full-speed USB-OTG, vector / SIMD instructions for ESP-DL neural-network inference, and an SPI / LCD / camera DMA path that earlier ESP32 modules lacked. With 8 MB PSRAM the N16R8 is the recommended variant for ESP-WHO face recognition, wake-word detection, and BLE-mesh gateways.
