The
PIC32 WFI32 Curiosity HPC Board includes headers to
mount different Ethernet PHY daughter boards to implement a complete Ethernet node for
networking. The
PIC32 WFI32 Curiosity HPC Board uses the
LAN8720A PHY daughter board (AC320004-3) as an example to demonstrate the Ethernet
functionality.

The Microchip LAN8720A PHY daughter board is populated with a small footprint RMII 10/100
Ethernet transceiver (LAN8720A). This daughter board enables Ethernet communication with a
variety of Microchip development boards. The following table provides the pin details and
descriptions of the Ethernet PHY daughter board header (
J405 and
J406).
