15. Pros •Extensible •Common Pinouts

16. Cons • Impossible to create a at scale prototype •

    Many extensions overkill for wearables
17. None

18. Pros • Inexpensive • Available GPS Module • Low Power

    • Aduino Based • Lots of Support

19. Cons • No easy way to integrate Bluetooth or Wifi

    • Requires a physical connection to get data • Things like an accelerometer require a separate component
