Waveshare CM IO Board with PoE for Pi CM3/CM3+/CM4S

Description

The Waveshare Compute Module IO Board with PoE Feature is a comprehensive development platform engineered to unlock the full potential of Raspberry Pi Compute Modules, specifically supporting CM4S, CM3, CM3L, CM3+, and CM3+L variants. This robust board serves as an essential interface for rapid prototyping and seamless deployment of embedded applications, providing critical I/O expansion and versatile connectivity options.

Central to its design is integrated Power over Ethernet (PoE) support, allowing for simplified power delivery and network access via a single Ethernet cable, adhering to the 802.3af standard. Beyond PoE, the board breaks out a wide array of interfaces including multiple USB ports, CSI camera interfaces, HDMI and DSI display outputs, and a dedicated USB to UART bridge for efficient serial debugging.

Further enhancing its utility, the board features a standard Raspberry Pi GPIO header, enabling developers to easily connect and utilize existing Raspberry Pi HATs and expansion modules. An onboard cooling fan interface, controllable via IO pins or automatic power-up, ensures stable operation under various workloads, making this IO board a foundational component for advanced embedded projects.
