## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Improper Lens Alignment
- Problem : Misaligned lens causes tracking inaccuracies and jumpy cursor movement
- Solution : Implement precise mechanical mounting features with ±0.1mm tolerance
- Verification : Use optical alignment fixtures during assembly
Pitfall 2: Inadequate LED Current Control
- Problem : Insufficient or excessive LED current affects tracking performance
- Solution : Implement constant current driver with 15-20mA typical operating range
- Compensation : Include temperature compensation for consistent illumination
Pitfall 3: Power Supply Noise
- Problem : Switching regulator noise interferes with sensitive analog circuits
- Solution : Use separate LDO regulators for analog and digital sections
- Filtering : Implement π-filters on power supply lines
Pitfall 4: Mechanical Vibration
- Problem : External vibrations cause false motion detection
- Solution : Implement mechanical damping and software filtering algorithms
- Isolation : Use vibration-absorbing mounting materials
### Compatibility Issues with Other Components
