Maintains the traditional physical tile interface...
augmented by ..
Sensing tile location and value
Automatically calculating and displaying scores
Maintaining player profiles
Validating words in the event of a 'challenge'
Exposing game stats over an external interface 2

5. Considerations Separate power branches for sensing circuits and pwms
Careful of having too much capacitance added to the sensing circuits (can probably be calibrated for, but best to be careful)
Some signal traces will need to be long, these will have to be carefully routed to avoid being side by side with long power traces
Since we won’t be sampling at high speeds, however, we can cheat on this a little
