EVK407I, STM32F4 Development Board

Overview

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.
