🔧 Integration Notes (Arduino / Raspberry Pi / Microcontrollers)

• Use a constant-current LED driver set to 350 mA for optimum performance and lifespan.
• Do not drive the LED directly from a microcontroller GPIO. Use a suitable driver module or a transistor/MOSFET with current regulation.
• PWM dimming is supported when the driver allows PWM input; ideal for brightness control via Arduino or Raspberry Pi.
• Provide adequate heatsinking. Although efficient, a 1 W emitter still dissipates significant heat—thermally couple the LED to a heatsinked PCB or metal surface.
• Observe polarity (anode/cathode) and ESD precautions during handling.

This 1W blue LED offers a strong balance of efficiency, optical output, and reliability, making it a versatile choice for custom lighting, signaling, and embedded systems where precise voltage and current control are essential.
