This 9V 1A Main Adapter PSU is designed to be used with almost all Arduino projects, and is the ideal solution for when you need to power your Arduino projects from an electrical wall outlet. Equipped with a centre-positive 2.1mm barrel Jack, this PSU plugs directly into the power ports of all Arduino boards, providing safe 9VDC and 1A to the circuit.

While most Arduino power supplies will provide at least 250mA, this PSU offers 1000mA to ensure that your circuit will be fully powered even when you include LED’s and other components. This is important because Arduino boards require a minimum of 250mA to run the microprocessor and vital parts, which means you will need more than just the minimum if you are adding more components to the circuit.
