## 🛠️ Expansion Interfaces: A True Industrial Solution

This board offers features designed not just for development but also for real-world deployment.

**PoE (Power over Ethernet) Support:** The optional PoE module allows both data transmission and power supply to be handled by a single Ethernet cable. This significantly reduces installation costs and complexity in remote locations without access to power outlets.

**Camera and Storage:** Built-in **OV2640/OV5640 camera interfaces** and a **TF card slot** enable immediate use in AIoT projects requiring image capture, video monitoring, and data logging.

**Pico Compatible Header:** Compatibility with the Raspberry Pi Pico header maximizes expandability by allowing the use of various existing HATs.
