The Dauphine is a computation, communications, and power distribution platform developed from our Clio B product and specifically designed to function in a maritime environment.
Dauphine has the computing power to be anything from a simple data switch and power hub to a robust navigation computer. Built-in functionality enables seamless connectivity between point-to-point and redundant ring networks making Dauphine ideal for platforms needing configurable smart hubs.
Furthermore, an expansion slot provides end users the option of adding navigation sensors to unlock autonomous mission planning and control.

Overview
Dauphine is outfitted with a variety of serial communication protocols such as RS-485, RS-232, 5VVTL, CAN-FD, and 10/100 switched Ethernet port in a variety of mappings. It also has General Purpose Input/Output (GPIO) ports that can be used as a remote control receiver and for Pulse wave modulation (PWM).
Dauphine features 4 independent power inputs, each with fault detection and feedback prevention. These power inputs can be fed to 3 independent (but tie-able) power distribution busses, one of which can be powered from an internal, adjustable 3.5A power supply for maximum flexibility.
Safe operation of Dauphine is assured by a comprehensive set of voltage taps, as well as high and low side current measurements on both the inputs and outputs.
