Product Description
The Ethernet Switch is a 5-port 10/100 Ethernet switch designed to integrate perfectly with the BlueROV2 and BlueBoat, providing three additional Ethernet ports to connect accessories. This switch was designed in collaboration with BotBlox and leverages their extensive expertise on Ethernet switches for robotics applications!
Why do I need an Ethernet switch?
An Ethernet network on the BlueROV2 connects the surface computer to the ROV’s onboard computer, providing a high-speed connection that carries telemetry data and video. There’s a lot of extra bandwidth available on that network that can be leveraged for other devices, like sonars, IP cameras, and sensors.
Ethernet allows multiple devices to be connected to the same network, you need an Ethernet switch to route data between these connections. This Ethernet switch does exactly that! With 5 ports, two are used to connect to the existing Fathom-X and Raspberry Pi computer in the BlueROV2 or Blueboat, leaving three additional ports for expansion!
You could add a multibeam imaging sonar, add an additional computer for dedicated computer vision processing, or connect a high-end IP camera for new video options.
How does it integrate?
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. Two RJ45 port connections are available to quickly connect the Fathom-X and Raspberry Pi through the switch, while the remaining connections are broken out to JST-GH connectors that follow the Blue Robotics Connector Standard. The board can be powered from a wide voltage input up to 60V and has low power consumption. Indicator lights show activity on each port.
The switch comes with an RJ45 to JST-GH adapter board to make it easy to connect your Ethernet device during testing, but we recommend 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.
