Microchip Technology EV46B51A LAN8720A PHY-PoE Daughter Board powers the PIC32 WFI32E Curiosity Board (EV12F11A) through Power over Ethernet (PoE) instead of USB while facilitating the data transfer between the PIC32 WFI32E Curiosity Board and a Personal Computer (PC). The daughter board is comprised of two main sections. The first is an IEEE® 802.3at Type 2 compliant PoE Powered Devices (PD) based on the PD70201 PoE Controller. The PD uses a flyback DC-DC topology that delivers 5V and up to 3A current for use in demanding high-power end applications through the PIC32 WFI32E Curiosity Board. The second section is the data transfer based on a high-performance 10/100 Ethernet Transceiver LAN8720A PHY compliant with IEEE 802.3/802.3u (Fast Ethernet) and ISO 802-3/IEEE 902.3 (10BASE-T). These features allow fast and easy data transfer between the PC and PIC32 WFI32E Curiosity Board, enabling various IoT applications.
IEEE 802.3at Type 2 PoE Power Sourcing Equipment (PSE) or PoE Midspan powers the board through the RJ45 input connector. The load is PIC32 WFI32E Curiosity Board. The Microchip EV46B51A LAN8720A PHY-PoE Daughter Board is connected to the load through the dedicated socket J208 of the PIC32 WFI32E Curiosity Board, and two power cables from the 2-pin connector J2 of the EV46B51A LAN8720A PHY-PoE Daughter Board to the 2-pin connector J201 of PIC32 WFI32E Curiosity Board.
