SparkFun Breadboard Power Supply Stick - 3.3V/1.8V SF_Materials Can't decide which Arduino isThis is a very simple board that takes a 4 9V input voltage and outputs a selectable 1. 8V or 3. 3V regulated voltage. All headers are 0. 1\" pitch for simple insertion into a breadboard. Input power can be supplied to either the DC barrel jack or the two pin header labeled + and . Output power is supplied to the pins labeled GND and VCC. Board has both an On Off switch and a voltage select switch (3. 3V 1. 8V). The two sets of four GND and VCC pins
