{"title":"Breadboard Power Supply Stick 5V/3.3V with Headers","handle":"sparkfun-breadboard-power-supply-stick-5v-3-3v-with-headers","url":"/products/sparkfun-breadboard-power-supply-stick-5v-3-3v-with-headers","description":"This compact regulator board makes it easy to power breadboard projects from a 6-12V supply. It provides a selectable regulated output of either 5V or 3.3V, making it handy for quick prototyping with common microcontrollers, sensors and logic circuits.Input power can be supplied through the DC barrel jack or the two-pin header labelled + and -. Output power is available on the pins labelled GND and VCC, with an onboard ON/OFF switch and a separate voltage select switch for choosing 3.3V or 5V.The 0.1\" pitch headers suit direct insertion into a breadboard. The two sets of four GND and VCC holes are spaced so that, when connected to SparkFun's Basic Breadboard, both power buses are powered. Documentation includes the schematic, Eagle files, an unregulated power supply tutorial and design files.Features:6-12V input voltage via barrel jack or 2-pin header3.3V or 5V regulated output voltageON/OFF switchOutput voltage select switchPower status LEDPTC fuse protected power0.1\" pitch headers for simple insertion into a breadboardTwo sets of four GND and VCC holes spaced to power both buses on a Basic BreadboardSpecifications:Input voltage: 6-12V input voltage via barrel jack or 2-pin headerOutput voltage: 3.3V or 5V regulated output voltageOperating current: 800mA Operating CurrentHeader pitch: 0.1\"Barrel jack: 5.5x2.1mm center positive barrel jackDimensions: 2.15x0.65\"A straightforward power stick for breadboard experiments where you need a quick, selectable 3.3V or 5V rail.","vendor":"SparkFun","product_type":"Breadboard Power Supply","in_stock":true,"options":[],"variants":[{"id":15771,"title":"Default Title","sku":"SF-PRT-21297","mpn":"PRT-21297","price":20.65,"on_sale":false,"in_stock":true,"available_quantity":57}]}
