And hey, it does exactly what it says on the tin. This real-time clock (RTC) is the most precise you can get in a small, low-power package. We've had a breakout board version of this RTC for a while had, but we want to make it even easier for people, so it now comes with STEMMA QT connectors for plug and play simplicity. Most RTCs use an external 32 kHz timing crystal that is used to set the time with low Maintain current draw. And that's all well and good, but these crystals have a slight drift, especially when the temperature changes (the temperature changes the oscillation frequency very very very slightly, but it adds up.) This RTC is in a powerful package because the crystal is in the chip. And right next to the integrated crystal there is a temperature sensor. This sensor compensates for frequency changes by adding or removing clock ticks so that timekeeping stays on schedule. This is the best RTC you can get, and now we have it in a compact, breadboard-friendly breakout. With a button cell plugged into the back, you can get years of precise timekeeping even if the main power is lost. Ideal for data logging and clocks or anything where you really need to know the time. A coin cell is required to use the battery backup features. We do not include standard size to make shipping easier for those abroad. To make life easier so you can focus on your important work, we took the sensor and mounted it on a breakout PCB along with support circuitry so you can run it on 3.3V (Feather\/Raspberry Pi) or 5 V (Arduino\/Metro328) logic levels can be used. In addition, you can easily connect it with two wires (plus power and ground). We've even included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus, so you don't even have to solder.
