It can power Arduino boards via the Vin pin or DC jack (ensure board regulator can handle 12V). It is not directly suitable for 5V devices like Raspberry Pi, but a step-down converter can be added. Common pairings include L298N motor drivers, 12V relays, and sensor modules.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eThe barrel jack is center positive (tip positive), matching most hobbyist electronics. If you need bare wires, cut the connector: red for positive, black for ground. Always check the current rating of your load; exceeding 2A may trigger the overload protection or cause overheating.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
