How do they work

Wafer Connector: Transmits signals and power supply for the camera, screen, and sensors.

Battery Dock: Provides stable power input and charging connectivity for the entire device.

Tactile Switch: Enables manual operations including power-on, photo capture, video recording, and reset.

Cooperative Logic: Battery dock supplies power → Tactile switch triggers commands → Wafer transmits signals → Camera functions normally.
