EthernetTo use the Ethernet port, a magjack and capacitor need to be connected.This is currently available only as a DIY project using this OSH Park Shared Circuit Board. PJRC is planning to offer this as a DIY kit in the near future. You can also make the connection by soldering wires.
These parts are recommended to build the Ethenet connection.
