## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Insufficient Current Limiting
- Problem : Direct connection to voltage source without current regulation
- Solution : Implement series resistors or constant current drivers
- Calculation : R = (V_supply - V_f) / I_f (typically 150Ω for 5V supply)
Pitfall 2: Incorrect Polarity for Bi-Color Operation
- Problem : Reverse polarity activation causing incorrect color display
- Solution : Implement proper switching circuitry with reverse protection
- Implementation : Use dedicated driver ICs or transistor switching networks
Pitfall 3: Thermal Management Issues
- Problem : Excessive current leading to premature LED degradation
- Solution : Maintain current below maximum rated 30mA per color
- Thermal Design : Ensure adequate PCB copper area for heat dissipation
### Compatibility Issues with Other Components
Microcontroller Interfaces
- Voltage Level Matching : Ensure compatibility between MCU output and LED driver requirements
- Current Sourcing Capability : Verify MCU can source/sink sufficient current (typically 20mA)
- PWM Compatibility : Supports PWM dimming with appropriate driver circuitry
Power Supply Considerations
- Voltage Regulation : Requires stable DC supply with minimal ripple
- Inrush Current : Implement soft-start circuits if switching multiple indicators simultaneously
- Grounding : Ensure proper ground return paths to avoid noise interference
### PCB Layout Recommendations
Component Placement
- Maintain minimum 3mm clearance from other heat-generating components
- Position for optimal viewing angle relative to enclosure window
- Consider service access for potential replacement
Routing Guidelines
