Pins labeled 5V\/GND 3.3V\/GND plug directly into the power lines.\u003c\/p\u003e\n\u003cp\u003eWhen you plug this board into a breadboard you must be aware that the unused power and ground pins will short if they are inserted into a bread board row. To avoid this problem, orient the board so that the unused power pins are left off the side of the breadboard. You can also orient the board sideways and utilize both 5V and 3.3V at the same time.\u003c\/p\u003e\n\u003cp\u003eUSB v2.0 specifies a max of 500mA at 5V. The on-board fuse limits the current to 500mA. Board has a handy On\/Off switch.\u003c\/p\u003e\n\u003cp\u003eComes as a \u003cstrong\u003ebag of parts\u003c\/strong\u003e kit and is easily assembled if you can follow the silkscreen indicators and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.\u003c\/p\u003e\n\u003cp\u003eCheck out our \u003ca href=\"http:\/\/www.sparkfun.com\/commerce\/tutorial_info.php?tutorials_id=103\" target=\"_blank\"\u003eUnregulated Power Supply Tutorial\u003c\/a\u003e!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKit Contains:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUSB type B connector\u003c\/li\u003e\n\u003cli\u003eTO-220 Voltage Regulator (LM317 1.5A max current)\u003c\/li\u003e\n\u003cli\u003ePTC Resettable Fuse\u003c\/li\u003e\n\u003cli\u003e100uF 35V Capacitor\u003c\/li\u003e\n\u003cli\u003e10uF 25V Capacitor\u003c\/li\u003e\n\u003cli\u003e0.1uF 50V Capacitor\u003c\/li\u003e\n\u003cli\u003ePower LED\u003c\/li\u003e\n\u003cli\u003eSPDT Slide Switch\u003c\/li\u003e\n\u003cli\u003e4pcs 0.1\" Header Pins\u003c\/li\u003e\n\u003cli\u003e330 Resistor 1\/6W\u003c\/li\u003e\n\u003cli\u003e390 Resistor 1\/6W\u003c\/li\u003e\n\u003cli\u003e240 Resistor 1\/6W\u003c\/li\u003e\n\u003cli\u003eBare PCB with Silkscreen Indicators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003ca href=\"http:\/\/www.sparkfun.com\/datasheets\/Prototyping\/USB-Breadboard-PowerSupply.pdf\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 1.25x1.25\"\u003c\/p\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":7544196673,"sku":"PRT-08376","price":13.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/08736-05.jpg?v=1445513598","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-breadboard-power-supply-usb-5v-3-3v","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
