AI-On-The-Edge-Cam: Esp32-S3 with PoE, SD, Camera

Description

What is it?

This is an ESP32-S3 development board (16 MB flash, 8 MB RAM) that is compatible with the AI-on-the-Edge-Device framework. It integrates Ethernet with PoE, a micro-SD card slot, a camera with WS2812B back-lighting LEDs, a Stemma QT connector, comprehensive battery management, and a low-power sleep mode that draws just 20 µA.

Why did you make it?

It was created because, some time ago, I came across a great edge-AI framework called AI-On-The-Edge-Device and, after some discussion with the creators, I decided to build this custom hardware. The main motivation was that the ESP32-Cam, which is mostly used with the framework, lacks good power and battery management, camera back-lighting, and Ethernet/PoE support.

What makes it special?

• Ethernet with PoE
• Camera with 4 × WS2812B smart LEDs for back-lighting
• Micro-SD card slot
• 20 µA sleep current
• Integrated battery charging, protection, and measurement
• External antenna support
• Stemma QT I²C connector for external sensors
• Compatible with Ai-on-the-edge-device Esp32-s3 branch
• Schematics available via Datasheet tab

Each package contains:

• 1 × AI-on-the-edge-cam board
• 1 × OV2640 camera module
• 1 × 2.4 GHz antenna
