Possible Shield Requirements Analysis

[jmccartney]

This thread will be used to discuss basic requirements for a possible shellmo shield.

What do you want your shellmo to do?
--------
I think some big questions that need to be answered is:

Logic voltage?

Do we support the bio wire? Requires MOSFET integration.

Do we support motor drivers?

How much of the Arduino do you want to utilize? How much do you want to leave for future expansion, shields.

Price point per shield? A rough guestimate I did today is the PCB for the shield including lead free hasl will cost about 3.50 US a board. This is JUST the PCB. So going from their not including build labor (we assume this is free since this is our hobby how much do you want to spend on a single board. Just so we can keep things sane lets just base things on 10 test units to start.

Help me come up with more questions at first, then we can start answering them and find the best solutions for each requirement. Then we can design.
