## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Issues
- Pitfall : Inadequate power supply decoupling causing measurement noise
- Solution : Implement 100nF ceramic capacitor placed within 10mm of VDD pin, plus 10μF bulk capacitor
Mechanical Mounting
- Pitfall : Improper mechanical coupling leading to vibration-induced errors
- Solution : Use rigid mounting with minimal flex, ensure direct contact with PCB surface
Temperature Management
- Pitfall : Ignoring self-heating effects in high-performance applications
- Solution : Implement thermal isolation from heat-generating components and consider temperature compensation algorithms
Signal Integrity
- Pitfall : Long trace lengths causing signal degradation in digital interfaces
- Solution : Keep digital lines shorter than 50mm and use proper termination
### Compatibility Issues with Other Components
Microcontroller Interfaces
- I²C Compatibility : Ensure microcontroller supports standard-mode (100kHz) or fast
