1. A Power over Ethernet (PoE) expansion board for Raspberry Pi5/CM5, supporting IEEE 802.3af/at network standards. Suitable for use with PoE routers or switches that support IEEE 802.3af/at network standards. Only one network cable is needed to connect the for to the Internet and power it. 2. Based on the for 40PIN GPIO interface 3. Supports PoE Ethernet power supply, supports IEEE 802.3af/at PoE network standards, and PoE power supply performance is more stable 4. Uses isolated switch mode power supply 5. Compact and easy to assemble PoE power input: 38V-57V DC input Power output: GPIO pin header: 5V 5A (MAX) Network standard: Support IEEE 802.3af/at PoE Color: blue Material: PCB Package Contents: 1 x POE Expansion Board Kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
