ESP32-S3 WiFi Video Module
Overview
The ESP32-S3 WiFi video module (model ESP32-NanoCam) is a compact, cost-effective AI vision solution with a dual-board modular architecture (core processing board + communication expansion board). The core board features the ESP32-S3 processor and a 2MP HD camera, supporting WiFi video streaming, AI vision recognition, and voice interaction — preinstalled firmware works out of the box.
Key features:
- 2MP HD camera (1600×1200@30FPS)
- AP + STA dual-mode WiFi real-time streaming
- 8 AI modes: cat face detection, face detection, color recognition, face recognition, QR code scanning, LLM voice chat (XiaoZhi AI), ESP-Claw voice control
- Onboard ES8311 audio (microphone + speaker), supporting voice interaction
- WS2812 RGB status LED
- Type-C one-click firmware upgrade
- Standard PH2.0 I2C / UART interfaces

Quick Start
1. Power On
Preinstalled firmware — the module creates its own WiFi hotspot on power-up:
- Connect phone/PC to the module's hotspot
- Open the provided page/App for live video
2. Two Modes
| Mode | Description |
|---|---|
| AP mode | Module creates its own hotspot, terminals connect directly |
| STA mode | Module joins an existing WiFi router, same network as terminals |
3. Host Connection
UART (Raspberry Pi / Jetson Orin):
ESP32 RX → Host TX
ESP32 TX → Host RXI2C: standard PH2.0 I2C — outputs face/color detection coordinate data.
4. Development
Type-C to PC for one-click firmware upgrade; switch AI modes via serial commands (cat face / face detection / color / face recognition / QR code / voice chat). See the complete command reference in the Serial Protocol Manual.
