This is a very simple board that takes a 6-12V input voltage and outputs a selectable 5V 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/5V). The two sets of four GND and VCC holes are spaced such that when connected to our Basic Breadboard both power busses will be powered. Note: Headers are not supplied. You will need to supply your own headers to connect this board to a breadboard. Check below for some breakaway header strips. Dimensions: 2.15x0.65" Features: * 6-12V input voltage via barrel jack or 2-pin header * 3.3V or 5V regulated output voltage * 800mA Operating Current * ON/OFF switch * Output voltage select switch * Power status LED * PTC fuse protected power * 5.5x2.1mm center positive barrel jack Documents: * [Schematic](https://cdn.sparkfun.com/datasheets/Prototyping/Breadboard Power Supply - 5-3.3SMDV14.pdf) * [Eagle Files](https://cdn.sparkfun.com/datasheets/Prototyping/Breadboard Power Supply - 5-3.3SMDV14.zip) * Unregulated Power Supply Tutorial * GitHub (Design Files) https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2015-03-14 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-04-02 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-04-04 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-10-25 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-11-25 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-11-29 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-12-09 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2016-12-13 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2017-03-31 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2017-04-06 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2017-11-24 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2017-11-28 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2018-05-05 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2018-05-11 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2018-05-15 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2018-10-30 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2018-11-21 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2018-11-27 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2019-03-15 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2019-03-19 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2019-07-04 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2019-07-09 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2019-11-29 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2019-12-03 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2021-02-10 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2022-02-21 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2025-04-11 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2025-04-14 https://elecena.pl/product/5058583/sparkfun-breadboard-power-supply-stick-5v-3-3v 2025-05-02
