4. सेटअप

4.1 बिजुली आपूर्ति

The ESP32-P4-POE-ETH development board supports two primary power supply methods:

• USB टाइप-सी: Connect a standard USB Type-C cable to the board's USB-C port and a power source (e.g., computer USB port, USB wall adapter). This port is also used for programming.
• ईथरनेट (PoE) मा शक्ति: If using the included PoE module, connect it to the board and then connect an Ethernet cable from a PoE-enabled switch or injector to the board's RJ45 port. This allows both data and power to be supplied over a single Ethernet cable.
