  • Ethernet Switch
  • Designed to be a perfect complement for the Fathom-X board
  • Comes with an RJ45 to JST-GH adapter board
  • Provides three additional Ethernet ports
  • Supply Voltage: 7 - 60 volts
  • Ethernet Speed: 100 Mbps

The Ethernet Switch is a 5-port 10/100 Ethernet switch designed to integrate perfectly with the Fathom-X Tether Interface Board, providing three additional Ethernet ports for accessories on the BlueROV2.

This switch was designed in collaboration with BotBlox and leverages their extensive expertise on Ethernet switches for robotics applications. The Ethernet Switch is designed to be a perfect complement for the Fathom-X board. It has the same dimensions and mounting holes so that it can stack on top.

The switch comes with an RJ45 to JST-GH adapter board to make it easy to connect your Ethernet device during testing, but it is recommended to solder splicing one of the included JST-GH cables to your device for long term integration on an ROV since a standard RJ45 connector does not fit through a cable penetrator hole.
