。Description。Who doesn't occasionally need power regulation? We certainly do， so we've designed the SparkFun BabyBuck Regulator Breakout to help us with just such a task. Featuring the AP63203 from Diodes Inc， this breakout board takes advantage of a 2A synchronous buck converter that has a wide input voltage range of 3.8V to 32V and fully integrated 125mΩ high-side power MOSFET/68mΩ lowside power MOSFET to provide high-efficiency step-down DC/DC conversion. All of this snuggled up in a low-profile， TSOT26 package that's integrated into a 0.4in by 0.5in board.。Unlike it's sibling， the BabyBuck sacrifices power option flexibility for space. Don't worry， though， because you can still use the plated through holes for input and output power. With some simple right-angle headers， you'll be up and running in no time.。Frequency Spread Spectrum(FSS)reduces EMI and a proprietary gate driver scheme resists switching node ringing without sacrificing MOSFET turn-on and turn-off times， which further erases high-frequency radiated EMI noise.。Get Started with the SparkFun Buck Regulator Hookup Guide。Features。Low-Profile Footprint。VIN 3.8V to 32V。VOUT 3.3V。Up to 2A Continuous Output Current。0.8V ± 1% Reference Voltage。22μA Ultralow Quiescent Current。Switching Frequency - 1.1MHz。Supports Pulse Frequency Modulation(PFM)。Up to 80% Efficiency at 1mA Light Load。Up to 88% Efficiency at 5mA Light Load。Fixed Output Voltage - 3.3V。Proprietary Gate Driver Design for Best EMI Reduction。Frequency Spread Spectrum(FSS)to Reduce EMI。Precision Enable Threshold to Adjust UVLO。Protection Circuitry。Overvoltage Protection。Cycle-by-Cycle Peak Current Limit。Thermal Shutdown

Description。Get with the times， already! 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 I2C， 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.。This 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.。There 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.。Note：。The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 sensor consider using the Qwiic Mux Breakout.。The SparkFun Qwiic connect system is an ecosystem of I2C 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.。Get Started with the RV-1805 Real Time Clock Module Guide。Features。Operating Voltage(Startup)：1.6V - 3.6V。Operating Voltage(Timekeeping)：1.5V - 3.6V。Operating Temperature：-40℃ - 85℃。Time Accuracy：±2.0 ppm。Current Consumption：22nA(Typ.)。I2C Address：0xD2。Supercapacitor for Backup Power。2x Internal Oscillators。2x Qwiic Connectors
