Integration Tips for Arduino & Raspberry Pi 🛠️

• Drive with a constant-current LED driver set to 600–700 mA for stable output. Avoid direct GPIO drive.
• If switching from a microcontroller, use a MOSFET or transistor stage with proper gate/base drive and a suitable power supply.
• Ensure thermal management (heatsink and airflow) due to the high current density.
• Use PWM for intensity control; keep peak current within the rated forward current and ensure proper duty cycle.
• Remember that 940 nm IR is largely invisible to human eyes; verify output with a camera sensor if needed.

Notes ⚠️

• The “Operating Power Rating: 100–150 mW” refers to optical radiant power, distinct from electrical input power.
• Observe ESD precautions when handling the LED.
• Do not look directly into the emitter at close range; IR radiation may not be visible but can still be intense.
