{"title":"SparkFun Breadboard Power Supply Stick - 3.3V/1.8V","handle":"sparkfun-breadboard-power-supply-stick-3-3v-1-8v","url":"/products/sparkfun-breadboard-power-supply-stick-3-3v-1-8v","description":"The SparkFun Breadboard Power Supply Stick provides clean, regulated 3.3 V or 1.8 V power directly to your breadboard. It accepts 4–9 V input via a DC barrel jack or 2-pin header, and outputs regulated voltage through pins spaced to power both rails of a standard full-size breadboard simultaneously.\n\nThe board includes an on/off switch, a voltage select switch (3.3 V / 1.8 V), a power status LED, and PTC fuse protection. All headers are 0.1″ pitch for direct breadboard insertion.\n\nKey Features\n\n\nSelectable Output – Switch between 3.3 V and 1.8 V regulated output\n\n4–9 V Input – Via 5.5 × 2.1 mm centre-positive barrel jack or 2-pin header\n\n800 mA Operating Current – Sufficient for most breadboard projects\n\nOn/Off Switch – Convenient power control without disconnecting\n\nPTC Fuse Protected – Resettable fuse guards against overcurrent\n\nPower Status LED – Visual confirmation of active power output\n\nDual Rail Power – Pin spacing powers both breadboard power buses at once\n\n\nSpecifications\n\n\nInput Voltage – 4–9 V\n\nOutput Voltage – 3.3 V or 1.8 V (selectable)\n\nMax Current – 800 mA\n\nBarrel Jack – 5.5 × 2.1 mm, centre positive\n\nDimensions – 54.6 × 16.5 mm (2.15 × 0.65″)\n\n\nIdeal For\n\nPowering 3.3 V or 1.8 V circuits on breadboards\nPrototyping with low-voltage sensors and microcontrollers\nReplacing battery packs with clean regulated power\n\n\n\nNote: Headers are not included. You will need breakaway header strips to connect this board to a breadboard.\n\n\nResources\n\nSchematic (PDF)\nEagle Files (ZIP)\nGitHub – Design Files\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12128,"title":"Default Title","sku":"SF-PRT-13157","price":20.84,"on_sale":false,"in_stock":true,"available_quantity":50,"option1":"Default Title"}]}
