Electrical and Thermal Design Notes for Engineers 🧪

• Drive using a constant-current LED driver set to 700 mA. Do not power directly from GPIO or a constant-voltage rail.
• When switching with a microcontroller (Arduino, Raspberry Pi), use a suitable N‑MOSFET or LED driver module; include proper gate drive and flyback protection if applicable.
• Provide adequate heatsinking to the copper base or a metal-core/“star” PCB with thermal compound to maintain junction temperature.
• Observe polarity and ESD precautions. The emission is invisible IR; avoid direct exposure to eyes. A camera can help verify emission.
• Ensure supply voltage headroom that accommodates the driver and the LED’s forward voltage (1.6–2.0 V).
