Integration and Driving Guidelines 🤖

• Use a constant-current LED driver set to 590–700 mA. Do not connect directly to a DC supply or to GPIO pins of Arduino/Raspberry Pi.
• PWM dimming: Modulate the driver (or a MOSFET stage) via a microcontroller for brightness control.
• Thermal management: Mount on a suitable heat sink/MCPCB with thermal interface material to keep junction temperature within limits ♨️.
• Polarity: Observe anode/cathode markings; drive only in forward bias within the specified voltage and current.
• ESD handling: Use anti-static precautions when soldering or installing.

Quick Bench-Testing Tip ⚠️

For brief testing only (not for continuous use), you may current-limit with a power resistor: R ≈ (Vsupply − Vf) / I, with resistor power rating P ≥ I²·R. A dedicated constant-current LED driver remains the recommended solution.
