🧰 Integration Tips for Arduino, Raspberry Pi, and Microcontrollers

• Use a constant‑current LED driver set to 590–700 mA; ensure your supply voltage allows for the 3.4–3.8 V forward drop plus driver overhead.
• Do not connect directly to GPIO pins of Arduino/Raspberry Pi. Employ a suitable LED driver module or a MOSFET-based constant‑current solution.
• Provide adequate heat sinking/thermal management for 3 W operation (e.g., metal‑core PCB or heatsink) to maintain safe junction temperatures.
• Observe polarity and practice ESD‑safe handling to protect the Epileds chip.
