The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A\/D measurement of battery voltage. In other words, it tells your microcontroller how much 'fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFuel gauge system for single-cell lithium-ion batteries\u003c\/li\u003e\n\u003cli\u003eCan be connected in circuit to monitor battery.\u003c\/li\u003e\n\u003cli\u003eHardware and Software Reset.\u003c\/li\u003e\n\u003cli\u003eI2C Interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eEagle Files\u003c\/li\u003e\n\u003cli\u003e\nDatasheet (MAX17043G+U)\u003c\/li\u003e\n\u003cli\u003eC Example Code\u003c\/li\u003e\n\u003cli\u003eParticle Photon Library\u003c\/li\u003e\n\u003cli\u003eArduino Project Example\u003c\/li\u003e\n\u003cli\u003eGitHub\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":54158661386558,"sku":"fqx1787258245593","price":8.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/4119\/4302\/files\/sparkfun-lipo-fuel-gauge-discontinued_1.jpg?v=1787258249"}],"url":"https:\/\/poshstylefashion.shop\/collections\/batteriespower.oembed","provider":"My Store","version":"1.0","type":"link"}
