## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues
- Pitfall : Excessive current consumption during sleep modes
- Solution : Implement proper GPIO configuration and peripheral shutdown before entering low-power modes
RF Performance Degradation
- Pitfall : Poor range and connection stability
- Solution : Follow impedance matching guidelines (50 Ω) and use recommended balun circuit
Memory Management
- Pitfall : Application crashes due to stack overflow
- Solution : Carefully allocate memory regions and monitor stack usage during development
Thermal Management
- Pitfall : Performance degradation in high-temperature environments
- Solution : Ensure adequate PCB copper pour and consider thermal vias for heat dissipation
### Compatibility Issues with Other Components
Antenna Selection
- Compatible with chip antennas, PCB trace antennas, and external antennas
- Requires proper matching network for optimal performance
- Avoid metallic components near antenna area
Crystal Oscillator
- Requires 32.768 kHz crystal for low-power operation
- 32 MHz crystal must meet ±20 ppm accuracy for RF performance
- Follow manufacturer's load capacitance recommendations
Power Supply
- Compatible with Li-ion batteries (2.0-3.6 V)
- Requires stable LDO or switching regulator with low noise
- Decoupling capacitors must be placed close to power pins
External Peripherals
- I²C, SPI, and UART interfaces compatible with common sensors
- GPIO voltage levels compatible with 1.8V and 3.3V systems
- Consider level shifting for mixed-voltage systems
