9V 1A Power Adapter for Arduino, 5.5 x 2.1 mm Plug

Overview

This 9 V 1 A power adapter is the standard way to run an Arduino board independently of a computer. It plugs into the barrel jack on an UNO R3, Mega 2560, Due, Zero or Leonardo and feeds the on-board regulator through a 5.5 × 2.1 mm centre-positive plug.

It also fits a long list of Schwinn elliptical exercise machines (A10, A15, A20, A25, A40, 101, 102, 103, 220, 230, 240, 420 and 430), which makes it a common replacement adapter well beyond the workbench.

A 100–240 V input range means it works on any mains standard with a suitable plug adapter, and the 150 cm (4.9 ft) cord gives real freedom in where the project sits.
