Compatibility
This PSU works with any device that accepts 12V DC input and draws up to 2A. 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.
Wiring Notes
The 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.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino or Raspberry Pi?
It is compatible with Arduino boards that accept 12V input, such as the Uno (via Vin or DC jack). For Raspberry Pi, you need a 5V supply; pair with a step-down module if you wish to use this PSU.
Can I use this to power 12V LED strips?
Yes, this supply is rated for 12V LED strips up to 2A (24W). Match the connector polarity or solder directly to the strip's power pads.
Is the output center positive?
Yes, the standard barrel jack is center positive (tip positive), which is the most common configuration for single-supply projects.
