ESP32-S3 AI CAM Development Board Camera with Night Vision

The DFRobot camera module combines an ESP32-S3 with 16 MB flash and 8 MB PSRAM, an OV3660 wide-angle camera with 160° field of view and infrared sensitivity, infrared illumination, a microphone and an amplifier for the included speaker. This allows image recognition directly on the module, for example with Edge Impulse, video streams via WLAN and voice dialogues with online services such as ChatGPT. Online services need an internet connection, an own account and possibly fees. Power is supplied via USB-C with 5 V or via VIN with 3.7 to 15 V.

Recommended Accessories:

• 16GB MicroSDHC Memory Card Class 10 UHS-I incl. SD Adapter

Features:
