We have 1 units in our Sydney Warehouse available for immediate dispatch.
This 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 pairs of GND and VCC pins are spaced such that when connected to our Basic Breadboard both power busses will be powered.

Note: We’ve released a new version of the SparkFun Breadboard Power Supply Stick, it can be found here! The new version functions the exact same way as this older model but we’ve made a few changes to footprints, the silkscreen, and added a second set of pins that output to the breadboard to help with stabilization. Go check it out!
