3.8 Ethernet PHY Header (J208)

The PIC32 WFI32E Curiosity Board includes headers to mount different Ethernet PHY daughter boards to implement a complete Ethernet node for networking. The PIC32 WFI32E Curiosity Board uses the LAN8720A PHY daughter board (AC320004-3) as an example to demonstrate the Ethernet functionality.
