A Rugged, Stackable Ethernet Switch Component

The UbiSwitch Module is a compact, modular high port-count ethernet switch designed for use in automotive, subsea and aerospace applications. This switch aims to be a standard modular component that system integrators can use to easily add ethernet connectivity to their systems, without adding significant size or weight.

UbiSwitch provide eight gigabit ethernet PHY ports and three 10 gigabit MAC ports on a stackable modular header, so that a system integrator can design a daughterboard with a specific combination of connectors. The 10 gigabit MAC ports also allow integration of optical SFP modules on the daughterboard.

This design is the culmination of hours of direct customer feedback, and hence aims to be a universal ethernet switch component that can be integrated directly into customer’s systems.

A Design for Aerospace and Deep Sea applications

To achieve the requirements of deep subsea as well as aerospace applications this design will have a focus on pressure tolerance, vibration tolerance and a wide ambient operating temperature. This ruggedness is achieved in the following ways.

  • Increased board thickness of 2mm to reduce standing susceptibily to high frequency vibration standing waves
  • Automotive or higher rated components to enable an extended temperature range of -40°C to 80°C
  • X5R or higher rated capacitors for reduced capacitor variability with temperature variation
  • Molex PicoClasp positive locking connectors with increased contact area to resist vibration
  • BGA chip underfill for pressure tolerance
  • Solid state cooling to prevent mechanical failure of moving parts
  • 0.8mm pitch stackable connector for increased clearance between signals

This ruggedness will be indepedently verified by way of MIL-STD-810-H testing for Temperature (low, high and shock), Pressure (low and high) and Vibration. 


The modular nature of this board will allow a wide variety of daughterboards to be designed, with widely varying combinations of connectors and PHYs to support different ethernet interfaces. In this way, this design aims to provide a ubiquitous solution to high performance, compact, rugged ethernet; addressing the underserved needs of next generation embedded systems.

Everying needed for ethernet connectivity other than the transformers and connectors in included on this board, allowing the customer to implement their own specific baseboard with minimal effort. 

To build a deployment ready system, we will be releasing a compact baseboard for UbiSwitch that breaks out all ports and power on easy to Molex PicoClasp connectors. This can be pre-ordered in the link below.
