🔌 Integration Tips (Arduino / Raspberry Pi)

• Use a constant-current LED driver (350 mA); do not drive directly from GPIO pins.
• For dimming, apply PWM control from a microcontroller through a suitable driver or MOSFET module.
• Observe the specified forward voltage (3.0–3.4 V) and ensure your supply and driver headroom are adequate.
• Provide proper heatsinking/thermal management to maintain performance and lifespan.
• For quick tests at reduced brightness, a series resistor may be used at lower currents; for full power, use a driver.
