PoE to USB-C PD Adapter
This board is designed to accept an IEEE 802.3bt Ethernet input with Power over Ethernet (PoE) and provide power to connected devices via USB-C Power Delivery, while maintaining uninterrupted Ethernet signal pass-through for data transmission.
The board negotiates power with Power Sourcing Equipment (PSE) and operates as a USB-C Upward-Facing Port (UFP) power source on the USB-C interface. It integrates full VBUS power monitoring circuitry, enabling precise measurement and supervision of voltage, current, and power on the USB-C supply rail.
The design is well suited for systems that require Ethernet connectivity and USB-C PD power input, but do not natively support PoE, enabling seamless deployment in PoE-powered network environments without additional external adapters.
