Design Tips and Usage Notes 🛠️

• Use a constant-current LED driver set to 300–350 mA; do not drive directly from a GPIO pin.
• Account for the LED forward voltage (3.0–3.4 V) when selecting your supply and driver headroom.
• Provide adequate thermal management (heatsink/star PCB with good thermal interface) to maintain reliability and brightness.
• Observe correct polarity and avoid reverse bias; handle with ESD precautions.
• For quick tests, a regulated supply with a properly calculated series resistor can be used, but a constant-current driver is recommended for long-term use.
