12V 2A Adapter

A regulated 12 volt adapter delivering up to 2 amps through a standard barrel jack. Twelve volts is the most common voltage in hobby and light industrial work, powering LED strips, small motors, pumps, relay modules and equipment generally. If you are powering an Arduino directly from this, be aware its regulator will run warm — 9V is gentler for that specific use. The most widely used voltage in hobby projects; 2A capacity for LED strips and small motors; Standard 2.1 mm centre-positive barrel jack; Regulated switching output
