Design & Integration Notes for Arduino/Raspberry Pi 🧠

• This device is not a logic‑level MOSFET; for full performance, drive the gate at ~10–12 V using a proper gate driver module when interfacing with Arduino, Raspberry Pi, or similar microcontrollers.
• Use a gate resistor and ensure VGS stays within ±20 V absolute maximum.
• Provide adequate heatsinking and consider thermal management to utilize the high current rating.
• For inductive loads (motors, coils), add a flyback diode or snubber for reliable operation.
• Keep high-current paths short and use low‑impedance PCB traces or bus bars to minimize losses and EMI.
