## Fundamental Board
The Fundamental Board is located just above the wristband; above it come the battery, the Harmonic Board, and the display. The Harmonic Board is connected to the Fundamental Board via a board to board connector.
The Fundamental Board is located just above the wristband; above it comes the battery, the Harmonic Board, and the display. The Harmonic Board is connected to the Fundamental Board via a board to board connector.
Several interfaces for [interhacktions](/en/interhacktions) are included on the Fundamental Board. The travelers can be alerted to an event using the vibration motor. Screws through the ECG contacts are used both for attaching the wristband and for making contact with your skin for ECG measurements. Besides its use for interhacktions, the [USB-C](/en/usbc) connector is also used for charging the battery and for updating the firmware.
