🤖 Integration with Arduino & Raspberry Pi

For safe operation with Arduino, Raspberry Pi, and other microcontroller-based systems, drive this LED using a constant-current LED driver module set to 600–700 mA. Do not connect the LED directly to GPIO or fixed voltage rails.

• Use a 700 mA constant-current driver; control brightness via PWM from your microcontroller.
• Provide adequate heatsinking to maintain performance and lifespan.
• Observe correct polarity and ESD precautions when handling the emitter.

📡 Typical Applications

• IR illumination for cameras, machine vision, and CCTV
• Sensing and optical experiments in the 730–740 nm band
• Prototyping with electronics components and driver modules
• DIY electronics projects with microcontrollers and single-board computers

🌡️ Handling & Thermal Guidelines

• Mount on a suitable heatsink or thermally conductive surface to manage junction temperature.
• Operate within 2–2.2 V at the rated current; always use current regulation.
• Follow ESD-safe handling; avoid reverse polarity.
• IR radiation may be invisible—avoid direct exposure to eyes at close range.
