Overview

The Hiwonder ESP32 S3-Cam is an AI-vision camera module based on the ESP32-S3 chip, designed for real-time image capture and wireless video transmission. It is suitable for IoT, robotics, smart-home, and other embedded-vision applications. The module supports WiFi streaming, basic on-board image recognition (e.g. face recognition, color detection, line tracking), and can interface with microcontrollers (e.g. Arduino, ESP32, Raspberry Pi) for expanded functionality.

Key Features

• Built on the powerful ESP32-S3 chip (dual-core 32-bit CPU up to ~240 MHz)
• Integrated 2-megapixel camera
• Real-time video streaming over WiFi (module acts as AP or STA)
• On-board support for AI vision tasks: face recognition, color detection, line tracking (with appropriate firmware)
• Communication ports: USB-C (for power and firmware upload), I²C/UART for secondary controller connection
• Compact size and simple wiring — ideal for robotics and DIY embedded projects
• Easy firmware upgrade via USB-C cable
