This project involves designing a PCB for the lid assembly of an open-source laptop. The design integrates various sensors, including a microphone, camera, and ambient light sensor, ensuring precise alignment with the display glass. It features touch sensors to control LED lighting, spring-loaded contacts for touch-key interaction, and 3D-printed light diffusers for efficient lighting. Additionally, the PCB includes a power management system with status LEDs and a PFC for connecting to the external laptop PCB. The goal is to create a versatile, upgradeable, and user-friendly component for the laptop's lid.
Specific parts of the project include
- Microphone - Audio input capture
- Ambient Light Sensor Module - Light intensity measurement
- Camera - Video capture
- LDO Regulators (3 TLV74 Series) - Voltage regulation for different components
- Crystal - Clock generation
- Touch Sensor Controller - Touch-key interaction
- Flip-Flop - State keeping in logic circuits
- LEDs (LTRBR37G Series) - Lighting indication
- FPC Connector - Interface with main laptop PCB
