ESP32-S3-WROOM-1-N16R8 Wi-Fi Bluetooth Module | AI Accelerator | IoT & Smart Home Ready

ESP32-S3-WROOM-1-N16R8 Wi-Fi Bluetooth Module | AI Accelerator for IoT & Smart Home

The ESP32-S3-WROOM-1-N16R8 is Espressif's flagship Wi-Fi 4 + Bluetooth 5 dual-mode module, combining a 320MHz single-core Xtensa LX7 CPU, 16MB Flash, and 8MB PSRAM for demanding IoT deployments. The integrated neural network accelerator (NPU) enables TensorFlow Lite compatibility on-device, making this module the natural choice for smart-home edge devices, industrial automation, and AI-driven IoT applications that need on-board inference rather than cloud round-trips.

Designed for the realities of field deployment, the module supports ultra-low power modes (Modem-sleep / Light-sleep) and operates across an industrial-grade -40°C to +85°C temperature range — the right envelope for battery-powered nodes and harsh-environment installations. Hardware-accelerated security (AES-256, RSA-3072) keeps device-to-cloud and device-to-device traffic protected end-to-end.

320MHz CPU + Neural Network Accelerator for AI-Driven Applications

• AI acceleration — on-chip NPU for image and voice recognition over 2.4GHz Wi-Fi (802.11 b/g/n).
• Expanded memory — 8MB PSRAM enables data-intensive tasks like sensor fusion and real-time inference.
• Multi-protocol support — Bluetooth Classic + BLE (A2DP/SPP) plus Arduino, ESP-IDF, and MicroPython toolchains.
• Robust security — hardware-accelerated AES-256 / RSA-3072 encryption.
• Global certifications — FCC / CE / SRRC compliant for worldwide deployment.

Where the ESP32-S3-WROOM-1 Fits

The combination of integrated radio, large memory budget, and on-board NPU makes this module the workhorse choice for next-generation IoT designs: smart speakers and voice-control devices, edge-vision systems with on-device classifiers, gateway hardware bridging BLE sensors to Wi-Fi networks, industrial monitoring nodes that run inference locally to cut latency, and any product where the bill of materials needs to stay tight. The 18×25.5×3mm SMD footprint reflows cleanly on a standard PCBA line.
