This SparkFun Real Time Clock (RTC) Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power (running at only about 22nA in its lowest power setting) so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the �battery.“ To make it even easier to get your readings, all communication is enacted exclusively via I\u003csup\u003e2\u003c\/sup\u003eC, utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1”-spaced pins in case you prefer to use a breadboard.\u003c\/p\u003e \u003cp\u003eThis RTC module’s built in RV-1805 has not one, but two internal oscillators: a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +\/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.\u003c\/p\u003e \u003cp\u003eThere is also the option to add a battery to the board if the supercapacitor just isn�t going keep your project powered long enough (keep in mind, the supercap can hypothetically make the board keep time for around 35 days), you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour\/minute\/second\/date will be maintained.\u003c\/p\u003e \u003chr\u003e \u003cp\u003e\u003cem\u003eThe SparkFun Qwiic connect system is an ecosystem of I\u003csup\u003e2\u003c\/sup\u003eC sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can�t hook it up wrong.\u003c\/em\u003e\u003c\/p\u003e \u003chr\u003e \u003cp style=\"text-align:center;\"\u003e \u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/qwiic-real-time-clock-module-rv-1805-hookup-guide\" class=\"btn btn-default\"\u003eGet Started with the RV-1805 Real Time Clock Module Guide\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eOperating Voltage (Startup): 1.6V - 3.6V\u003c\/li\u003e \u003cli\u003eOperating Voltage (Timekeeping): 1.5V - 3.6V\u003c\/li\u003e \u003cli\u003eOperating Temperature: -40°C - 85°C\u003c\/li\u003e \u003cli\u003eTime Accuracy: ±2.0 ppm\u003c\/li\u003e \u003cli\u003eCurrent Consumption: 22nA (Typ.)\u003c\/li\u003e \u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC Address: 0xD2\u003c\/li\u003e \u003cli\u003eSupercapacitor for Backup Power\u003c\/li\u003e \u003cli\u003e2x Internal Oscillators\u003c\/li\u003e \u003cli\u003e2x Qwiic Connectors\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/5\/7\/0\/4\/6\/SparkFun-Qwiic-RTC-Module.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/d\/f\/a\/9\/e\/SparkFun-Qwiic-RTC-Module.zip\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/qwiic-real-time-clock-module-rv-1805-hookup-guide\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/1\/8\/9\/e\/2\/RV-1805-C3.pdf\"\u003eDatasheet\u003c\/a\u003e (RV-1805)\u003c\/li\u003e \u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/c\/a\/c\/6\/f\/DSK-414_SuperCap.pdf\"\u003eDatasheet\u003c\/a\u003e (DSK-414)\u003c\/li\u003e \u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/8\/4\/2\/f\/RV-1805-C3_App-Manual.pdf\"\u003eApplication Manual\u003c\/a\u003e (RV-1805)\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eQwiic Page\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_RV-1805_Arduino_Library\"\u003eArduino Library\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/Qwiic_RTC_Module\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
