Waveshare Power Over Ethernet PoE Board, Compatible with Raspberry Pi Compute Module CM3/CM3L/CM3+/CM3+L

• The Compute Module PoE Board is a development board which you can plug a Raspberry Pi Compute Module into, and make use of the resources of Pi more flexibly. With the PoE (Power over Ethernet) feature, and versatile onboard peripheral interfaces, it is suitable for evaluating the Raspberry Pi compute module, also is an ideal choice for end products.
• Raspberry Pi GPIO header, for connecting sorts of Raspberry Pi HATs. 10/100M auto-negotiation Ethernet port, with PoE enabled.
• 4x USB ports, allows connecting more USB devices. 2x CSI camera interfaces.
• Onboard HDMI / DSI interfaces for connecting displays. Onboard USB TO UART, for serial debugging.
• Cooling fan interface, auto run on power up OR controlled by IO pins. Adopts isolated SMPS (Switching Mode Power Supply).
