Features
The Compute Module PoE Board is a development board that 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.
1. Raspberry Pi GPIO header, for connecting sorts of Raspberry Pi HATs.
2. 10/100M auto-negotiation Ethernet port, with PoE enabled.
