12. Software
13. Options
15. Pros •Extensible •Common Pinouts
16. Cons • Impossible to create a at scale prototype • Many extensions overkill for wearables
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
24. Features • Bluetooth Support • Robust API for Android and IOS • Built in Sensors (temperature, accelerometer etc.) • Built in support for rechargeable batteries
25. Specs • ! Nordic Semiconductor nRF51822 BLE SoC • ! 2.4 GHz transceiver • ! ARM®Cortex™-M0 32 bit processor • ! 256 kB flash program memory • ! 16 kB RAM • ! 8/9/10 bit ADC
26. Specs Continued • Accelerometer • Temperature Sensor • Push Button Switch • Bright LED • Driver for vibration motor • micro usb chargable • I2C bus, and support for 4 digital/analog and 4 digital pins
29. Cons • Really Small • Tough to write custom drivers • Proprietary
31. Bluetooth • Same Frequency range as 2.4 Gigahertz Wifi • 79 Channels VS 13 • Less Throughput
32. Bluetooth LE • Always off • Less Throughput • Often lower transmit power • Designed for low data low power Applications
35. IOS • IPad 3rd Generation or better • Iphone 4S or greater
36. Android • Bluetooth 4.0 supported radio • Android 4.3 or greater
