ROSS EBox Auxillary

Version 1 of the Auxillary Board during testing.

 

Board Summary

Version 3 of the Auxillary board.

The Auxillary Board was created as a “catch all” to support kayak operations. It performs functions that were otherwise left out of other systems designed into the Electronics Box on the kayak. The board performs 3 primary operations: kayak winch control (optional), “Remote Start” and “Remote Kill” functionality, is a “USB to Serial” bridge for the Flight Management Unit (FMU) (or any other single device that requires it). It was originally an assimilation of projects by Corwin Perren (www.caperren.com) and Robert Shannon. It’s Teensy enabled!
