# Automotive ethernet

The FMU has a [TJA110x](https://www.nxp.com/products/analog/interfaces/in-vehicle-network/ethernet/automotive-ethernet-phy-transceivers:ETHERNET-TRANSCEIVERS) two wire automotive ethernet ([100BASE-T1](https://en.wikipedia.org/wiki/Fast_Ethernet#100BASE-T1)) transceiver . However, this is not yet supported by PX4. Adding driver support to PX4 and implementing the protocol might become a HoverGames task/challenge in the future.
