{"product_id":"pl4-com-13716","title":"FemtoBuck LED Driver","description":"\u003cp\u003eThis is the FemtoBuck, a small-size single-output constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V while the dimming control can be either accessed via PWM or analog signal from 0-2.5V. This board is based off of the [PicoBuck LED Driver](https:\/\/www.sparkfun.com\/products\/11850), developed in collaboration with Ethan Zonca, except instead of blending three different LEDs on three different channels the FemtoBuck controls just one.\u003c\/p\u003e\n\n\u003cp\u003eFor the FemtoBuck, weve increased the voltage ratings on the parts to allow the input voltage to cover the full 36V range of the AL8805 driver. Since the FemtoBuck is a constant current driver, the current drawn from the supply will drop as supply voltage rises. In general, efficiency of the FemtoBuck is around 95%, depending on the input voltage. On board each FemtoBuck you will find two inputs for both power input and dimming control pins and an area to install a 3.5mm screw terminal. Finally at either side of the board you will find small indents or \"ears\" which will allow you to use a zip tie to secure the wires to the board after soldering them down. This version of the FemtoBuck is equipped with a small solder jumper that can be closed with a glob of solder to double the output current from 330mA to 660mA.\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [Schematic](https:\/\/cdn.sparkfun.com\/datasheets\/Components\/LED\/femtobuck_v12.pdf)\u003cbr\u003e\n* [Eagle Files](https:\/\/cdn.sparkfun.com\/datasheets\/Components\/LED\/femtobuck_v12.zip)\u003cbr\u003e\n* [Hookup Guide](https:\/\/learn.sparkfun.com\/tutorials\/femtobuck-constant-current-led-driver-hookup-guide-v12)\u003cbr\u003e\n* [All About LEDs](https:\/\/www.sparkfun.com\/leds)\u003cbr\u003e\n* [Datasheet](https:\/\/cdn.sparkfun.com\/datasheets\/Components\/LED\/AL8805.pdf) (AL8805W5)\u003cbr\u003e\n* [GitHub](https:\/\/github.com\/sparkfun\/FemtoBuck\/tree\/V_1.2) (Design Files)\u003c\/p\u003e\n\n\u003cp\u003e**Videos**\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39705350209717,"sku":"PL4-COM-13716","price":31.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/13716-01.jpg?v=1618237136","url":"https:\/\/getcahits.com\/zh\/products\/pl4-com-13716","provider":"PuriLite","version":"1.0","type":"link"}
