Hardware schematic

12 Dec

Here below is a brief schematic over the hardware parts in the prototype bracelet. Most of the components are visualized with only their pins. However, the schematic will give a good overview of what’s put together.

Brief explanation: The YellowJacket module works almost like an Arduino, but has an onboard WiFi-device. The YellowJacket is connected to an OLED display (using serial communication), a push button and a vibrating DC motor. The circuit is powered with a 1-cell Li-Po battery (~4V, 600mAh) but since most components need 5V to work properly, a voltage booster device is connected between the battery and all other components (providing a steady 5V supply).
