Design Notes for Engineers & Makers 💡

• When driving from Arduino, Raspberry Pi, or other microcontrollers, use a suitable base resistor to set base current.
• Always add a flyback diode across motors, relays, and other inductive loads.
• Mount on an appropriate heatsink to achieve the specified 65 W dissipation and maintain reliability.
• Respect the device’s Safe Operating Area (SOA), especially for linear operation or high duty‑cycle loads.
