- Solution: Implement proper termination and controlled impedance routing
- Pitfall: Crosstalk between adjacent signal traces
- Solution: Maintain 3W rule spacing and use ground shielding
Thermal Management:
- Pitfall: Overheating under continuous maximum load
- Solution: Incorporate thermal vias and consider heatsinking for high-power applications
### Compatibility Issues with Other Components
Digital Interfaces:
- I²C/SPI compatibility requires level shifting when interfacing with 5V systems

- Place decoupling capacitors within 5mm of power pins
Signal Routing:
- Route critical signals (clocks, high-speed data) first with minimal length
- Maintain consistent characteristic impedance for high-speed traces
- Avoid 90-degree bends use 45-degree angles or curves instead
Thermal Management:
- Use thermal relief pads for soldering while maintaining thermal conductivity
- Incorporate thermal vias under the
