| It seems the [[http://www.pjrc.com/teensy/|"Teensy"]] may be the best board for the jobs. The board retains a USB connector, so will be easy to update/troubleshoot. | It seems the [[http://www.pjrc.com/teensy/|"Teensy"]] may be the best board for the jobs.

| - | Display Unit: the main unit should have two or three RS232 NMEA0183 inputs. First function button should scroll through those inputs, a long hold should change the number of inputs on the display (i.e. one input, two inputs side by side, two inputs vertical, three inputs, etc.). Ability to set input type (depth, speed, location, others?). | + | Display Unit: the main unit should have two or three RS232 NMEA0183 inputs.

| Speed sender: leads to the reed switch in the sender are the simplest to extend, so a teensy should be enclosed along with power toggle, and calibration momentary switches. Output of the teensy should be NMEA0183 serial over RS232. | Speed sender: leads to the reed switch in the sender are the simplest to extend, so a teensy should be enclosed along with power toggle, and calibration momentary switches.
